BricsCAD (Linux) releases

Version 13.1.19

Wed, 06 Feb 2013 17:13:51 UTC

Fixes

SR38661 - RPM INSTALLER: Libgnutls.so.26 has been added as a dependency of our RPM installer.
SR38641 - PRINT, RENDER CRASHES ON NVIDIA: Corrected initialization for rendering and printing on NVIDIA cards. OGL initialization turned out to be very sensitive to hardware differences.

Version 13.1.17

Fri, 01 Feb 2013 20:14:02 UTC

Fixes

SR34481, SR38120, SR38133 - SHADE PLOT: BricsCAD (Linux) crashed when using shade plot. Shade plot is implemented with multidevice printing, which did not work on linux. Multidevice printing has been fixed. As a result, crashes for shade plot are avoided. However, some hardware and driver dependent crashes can still occur. Indeed, we had to implement hardware and driver specific behaviour to avoid more specific crashes. Please report in a support request if your system still has problems with shade plot.
SR35899 - LISP: BricsCAD (Linux) crashed when loading a sufficiently large Lisp file during startup, for instance when loading MenuLisp files .mnl inside a DES project.
SR38120 - BMHARDWARE: Standard X-Hardware parts (screws, nuts, bearings, ...) can be used as mechanical components.
SR38120 - FOCUS STEALING: BricsCAD (Linux) grabbed focus when mouse hovered its main window even when other applications' windows were in front.
SR38120, SR37297 - PDF: The commands PDF, PDFATTACH, PDFCLIP, PDFUNDERLAY now work on Linux.
SR38120, SR38614 - TOOLPALETTES: Toolpalettes are enabled again in BricsCAD (Linux).
SR38141 - ACISIN: Bricscad(Linux) crashed during ACISIN command.
SR38195 - LISP ENTMAKE: A crash happened when calling ENTMAKE in a custom join routine written in lisp. The crash was caused by a recently added unsafe string comparison in internal function cma::OdDbObject_RbFiler::readLastSubclass. Added a NULL pointer check to avoid the crash.
SR38309 - AUTOCOMPLETE: Fixed autocomplete always required a selection from the list before acknowledging a command, unless the full command was typed.
CHAPOO: Connecting with Chapoo did not work in BricsCAD(Linux). It has now been fixed, and several chapoo-related features have been added.
TRANSLATIONS: Translated versions need a (system-level) locale to work properly. Installation of the proper locale has been added as post-installation step. Also, if the required locale is missing, BricsCAD will now display a warning.

Version 13.1.14

New

MCAD ASSEMBLY MODELING - (Platinum version only):

Uses .dwg files organized in hierarchical structures of mechanical components to model complex products. Example projects are provided in the \Samples\Mechanical folder.
Standard X-Hardware parts (screws, nuts, bearings, ...) can be used as mechanical components.
MECHANICAL BROWSER: browse the component hierarchy.
BILL OF MATERIALS: list top-level or bottom-level mechanical components used in a drawing.
ASSEMBLY CONSTRAINTS: apply 3D constraints between faces and edges of different mechanical components.
KINEMATIC ANALYSIS: use DmMove and DmRotate commands for real-time solving of forward and inverse kinematic problems.
Assembly Modeling commands:
- BmBrowser: toggle the visibility of the Mechanical Browser
- BmUpdate: update the hierarchy of mechanical components for the current drawing
- BmNew: create a new mechanical component as a new drawing document
- BmInsert: insert an existing mechanical component into the current drawing
- BmForm: form a new mechanical component and insert it into the current drawing
- BmDissolve: dissolve a mechanical component inserted into the current drawing
- BmMech: convert the current drawing into a mechanical component
- BmUnmech: convert the current mechanical component into a plain drawing
- BmHardware: insert a standard hardware part as a mechanical component
- BmHide: hide a mechanical component inserted in the current drawing
- BmShow: show a hidden mechanical component
- BmBom: insert the Bill-of-Materials (BOM) table into the current drawing
- BmXConvert: convert all X-Hardware solids present in the current drawing into mechanical components

3D CONSTRAINTS:
- Constraints can now be imposed between sub-entities of block references.
- Constraints are now maintained on COPY/COPYCLIP/PASTECLIP/BLOCK/INSERT/EXPLODE/WBLOCK commands.
- DMANGLE3D: the axis for 3D angle constraints can now be chosen (automatically or manually), allowing to change the angle parameter over 180 degrees.
ARRAY dialog: offers control and feedback for the various array command settings.
ATTRIBUTES:
- ATTREDEF: command for redefining attributes of existing blocks.
- ATTSYNC: command for synchronizing attributes of block inserts whose attribute definitions were modified.
- BATTMAN: dialog for managing attribute definitions of existing blocks.
- Added support for Locked position and Multiline properties of attribute entities.
AUTOCOMPLETE: command line auto completion.
CHAPOO has been integrated into BricsCAD. CHAPOO allows to upload, share, view, annotate drawings and documents. Chapoo will become functional when the servers become available online.
- Commands: CHAPOOOPEN, CHAPOOACCOUNT, CHAPOOLOGON, CHAPOOLOGOFF, CHAPOOHOME.
DIMREASSOCIATE: command for (re)associating dimensions to existing entities.
DIRECT MODELING:
- DMMOVE/DMROTATE commands can now be applied to block references.
- DMREVOLVE/DMEXTRUDE: can now be applied to faces of solids.
- DMROTATE/DMREVOLVE: cylinders and other axial surfaces can now be used as rotation axis.
- DMSELECTEDGES: Quad command for faster 3d solid edges selection.
DYNAMIC UCS: dynamically align the UCS with faces of 3D solids when hovering over these faces during execution of commands.
- UCSDETECT system variable controls activation of dynamic UCS detection.
- Press the F6 key or click the DUCS field on the status bar to toggle UCS detection On/Off.
HIDE: enabled the HIDE command in paperspace and added the 'Hide paperspace objects' option to the Print settings.
MLINE: command for multiline creation. Support for snapping and grip-editing of multilines has been added.
MLSTYLE: command for creating and editing multiline styles.
PARALLELIZATION: enabled multi-threaded display regeneration, using multiple processor cores. MTFLAGS and MAXTHREADS system variables were added to control multi-threading aspects.
PRINTING:
- SHADE PLOT: property for paperspace and modelspace viewports . This property is applied during printing, it overrides the visual style of a viewport.
- Enabled printing of layouts containing combinations of viewports using different visual styles.
- DISPPAPERMARGINS: system variable to control the display of the printable area.
- SR28726, SR29997, SR33003, SR33335, SR33890 and others - PRINT: implemented support for fine-tuneable printing of transparent images. When a problem is encountered while printing transparent images to a certain printer type, the ImagePrinting.xml configuration file in the plotter configuration folder now offers improved control by allowing to override the default settings with specific per-printer settings. The file contains documentation on how to use it.
- SR34409 - PRINT: added support for plot style's line-end caps and joints in plot and plot preview.
- TrueType fonts can now be printed as text instead of geometry, which makes them searchable in PDF prints and which reduces the size of the print output. This is controlled by the "Truetype Text" setting in the PC3 file, and if no PC3 is used, by the system variable TTFASTEXT.
  If TEXTFILL is off, text is always printed as geometry.
PUBLISH:
- BACKGROUNDPLOT: system variable controls whether documents are published in the current session or in a BricsCAD session running in the background, thus allowing to continue drawing while printing.
- /pl command line switch has been added for background (silent, without showing the main program window) publishing using DSD files. Format is '/pl [[path]name[.ext]]'. If the file name parameter is absent, the program just exits. If the file extension is absent, ".dsd" is added to the filename. File searching is done according to usual OS rules. If the DSD file is found, publishing is invoked according to the DSD file, and upon completion the program exits. When BricsCAD is started with the '/pl' switch, it ignores the SingletonMode setting thus allowing multiple instances.
- Page Setups from other drawings can now be imported.
- SR35875: added 'Move Sheet(s) Up/Down' and 'Reverse Sheet Order' buttons and functionality.
QLEADER: command and dialog were added. They allow to avoid specifying the same leader options over and over again.
SHEET SETS:
- Commands: SHEETSET, NEWSHEETSET and OPENSHEETSET.
- System variables: SSFOUND, SSLOCATE, SSMSTATE.
TOOLBAR COMBO BOXES: have been added for layer filters, layer states and dimension styles. All toolbar combo boxes now have adjustable width.
TOOLPALETTES, WORK IN PROGRESS: Toolpalettes have been enabled on linux. Mind that this is work in progress: follow up fixes for this platform will be needed.
VIEWPORTS:
- MVSETUP command
  - Model layout: set up the unit type, drawing scale factor and paper size.
  - Named layout: create, align and scale a set of layout viewports.
- ALIGNSPACE: command to adjust viewport angle, zoom factor and pan position based on alignment points specified in model space and paper space.
WALKTHROUGH NAVIGATION (for perspective views):
- Alt + Left Mouse Button to 'walk' forward/backward and sideways, using the new RTWALK command.
- Alt + Middle Mouse Button to move up/down and sideways, using the new RTUPDOWN command.
- Ctrl + Middle Mouse Button to look around, using the new RTLOOK command. Shift + Right Mouse Button now brings up the snap menu instead of the former Ctrl + MMB combination.
- Ctrl + Home key sets the view direction to horizontal.
- Alt + Home key moves the target point to the center of the scene/drawing.
- Alt + Plus/Minus keys from the numeric keypad = increment/decrement movement speed, by modifying the new RtWalkSpeedFactor preference setting.
- Ctrl + Plus/Minus keys from the numeric keypad = increment/decrement rotation speed, by modifying the new RtRotationSpeedFactor preference setting.
WORKSETS: command for working with named groups of drawings.
Upgraded RedSdk rendering engine to version 3.1.0.4
Upgraded to V3.6 Open Design Teigha libraries.

Improvements

3D CONSTRAINTS: improved the DMANGLE3D initial angle value computation and dynamic dimension positions.
RENDERING: improved RedSDK hardware detection, such that when hardware rendering is not possible, BricsCAD can switch to software rendering more gracefully.
SELECTION: selection commands now need to explicitly set a ":N" option in order to be able to select nested entities.
SHADING: improved gooch shading:
- the backside of double sided OdDbFace objects was drawn in a dark color, unlike the front side of the object.
- dark objects were tinted green.
SUBENTITY SELECTION: enabled selecting and TAB-cycling through faces and edges of nested solids in block references.
WARNINGS: following warning messages can now be suppressed by checking a 'Don't show this again' checkbox:
- message when moving entities to a frozen or turned off layer
- message when saving to a previous version that doesn't support some entities
- the 'WarningMessages' preference is used to store whether these messages should be shown or not.
SR27347, SR28240 - DIMENSIONS: added support for creation of associative dimensions using NEAREST snap.
SR29126 - DIMENSIONS: the dimstyle's DIMLFAC was not applied when dimensioning a modelspace entity in paperspace.
SR32046 - PRINT: improved print output for TTF fonts that require a non-standard approach for rendering the character glyph contours. The improvement is not applied when clipping is involved, e.g. with viewports or xrefs.
SR32692, SR34446, SR35215 - OFFSET: added command options LAYER, UNDO and EXIT.
SR33450, STARTUP DIALOG: in the startup dialog, dwg files that are not in the template path could be listed in the list of template files. Restricted the template file search to the template path and its subdirectories only.
SR33737 - DIRECT MODELING: improved the behavior of DMPUSHPULL on models with constrained cylindrical fillets.
SR34472 - LAYER STATES: when a layer state is imported, a message box is displayed asking the user if the imported layer state should be restored.
SR34685 - SELECT: corrected an issue where multiple selection returned an error code when the user canceled the operation.
SR34938, SR34975 - LAYER: the MATERIAL option was added for the -layer command.
SR35159 - COPY: when pressing and holding down the Ctrl key while dragging a selection set, the selection set is copied instead of moved when the mouse button is released.
SR35517 - DYNAMIC PROPERTIES: different visibility of same dynamic property with multiple entities selected was dependent on order of selection.
SR35544 - APPLOAD: renamed "Select LISP or DRX Files" dialog to "Select Application Files". This dialog opens when clicking the 'Add...' button in the 'Load Application Files' dialog.
SR36254 - PDFEXPORT: strongly reduced size of PDF files with embedded TTF fonts, by omitting the definitions of unused character glyphs.
SR36419 - 3DCONTEXT: when using the 3Dcontext command, a warning message will now pop up if hardware-based rendering is not supported.
SR36711 - TABLE: table cell margins can now be set in the properties palette, when a cell or range of cells is selected.
SR37306 - CUSTOMIZE DIALOG: when modifying the 'Help', 'Command' or 'Image' property of a menu item, toolbar button, keyboard shortcut, mouse button or double-click action, a warning message now appears that in fact the tool definition itself is being modified.
SR37350 - MENU: the menu shortcuts stopped working after using MENULOAD without a dialog.
SR37360 - LAYER: when the Layer Explorer opened for the first time, the layers were incorrectly sorted.
SR37501 - ERROR ON OPEN: improved error handling when new document can not be created because of an unsupported template file format. Now a warning message is shown, and a new document is created from scratch
SR37552 - WIPEOUT: it was not possible to use shortcut "of" in the WIPEOUT command. Shortcuts 'on' and 'off' have been added to the frame option of the wipeout command.

Fixes

V13 contains hundreds of fixes that have become available by upgrading to V3.6 of the Open Design Teigha libraries. These fixes are not listed here.
Instead of loading the FreeType library from the system directories, it is now correctly loaded from the custom installed version.
DELCONSTRAINT: not all constraints were deleted on two closed polyline triangles having constraints on them. Also, Delconstraint performance has been improved for drawings containing a large number of constraints.
DIRECT MODELING: DMPUSHPULL reference faces were incorrectly sorted in the TAB-cycle.
DRAWING EXPLORER - Page Setups: an exception occurred in scenario: Drawing Explorer/Page Setups > Page Setup dialog > Preview > close using the Esc key.
DRAWING EXPLORER - Views, Background combo: when the 'Image' option was selected the first time, a bogus error message box appeared - "Can't load image from file ''".
LAYERFILTERS: instead of color names, color indices are now stored in layer filter definitions.
PDFUNDERLAY: last segment of closed polyline was ignored during snapping.
TEXTSCREEN: upon startup, the textscreen should not appear even if WNDLTEXT is on.
SR16294 - DRAWING EXPLORER, Images: disabled 'Rename' option in 'Edit' and context menu (Images cannot be renamed).
SR19619, SR30249, SR35892 - RASTER IMAGES: when interpreting image geo referencing world files (such as .tfw and .jgw files), the image origin, scale and rotation were incorrect.
SR21745 - CURSOR: aperture box was visible when no command was active.
SR23409 - DIMARC: creation failed for arcs at large coordinates.
SR24910 - RASTER IMAGES: OpenGL graphics device always used black foreground color for bitonal images, instead of the color of the entity.
SR25031 - DIMENSIONS: DIMARC entities in layouts ignored DIMLFAC value.
SR28120 - VIEWS: on creation of a view, when the ratio between the view's width and height was greater than the ratio between screen width and screen height, the view's height was adapted and stored accordingly. Now the value stored for the view height is no longer modified, but when the view is set current, the viewport height will be adjusted according to the screen size.
SR28616 - RASTER IMAGES: when an image was inserted at large coordinates, the image disappeared and reappeared while zooming in/out.
SR29800 - PROPERTIES BAR: the scale of blocks set to 'Scale uniformly', could not be modified from the Properties Bar.
SR30056 - BLOCKS: an exploded block, inserted from disk, was not displayed during dragging.
SR32206 - ATTEDIT DIALOG: attributes were not updated in the drawing upon pressing the Apply button.
SR32741 - PDF UNDERLAY: a crash occurred when opening user-provided drawing with PDF underlay.
SR32918 - 2DCONSTRAINTS: angular constraint for an orthogonal pair of lines or points gave undesirable result.
SR33007 - CONSTRAINTS: glyphs that depend on a UCS to make sense now show a different bitmap if the current UCS is not parallel to the one they were created in. For example, if a line was made horizontal in WCS and then the UCS is changed to be at an angle, the line appears to be at an angle to the UCS-X (but horizontal in WCS), thus causing confusion. This is addressed by showing a different horizontal bitmap with small blue UCS axes.
SR33021 - DIMENSIONS: associative rotated dimensions disappeared (collapsed) after modification (e.g. STRETCH) of the dimensioned entities.
SR33277 - DWGPREFIX: when a new/unsaved drawing is opened, the DWGPREFIX variable should point to the BricsCAD startup folder.
SR33898 - DISPLAY: the cursor pickbox was not undrawn when a command was started, it was undrawn only after a mouse movement occurred. This was not always reproduced, usually it occurred with commands without pop-up menu (e.g. start of LINE).
SR33919, SR34562, SR34897, SR34898 - HATCH: fixed TRIM problems.
SR34472 - LAYER STATES: after importing a layer state file (.las) and then switching to the Layer view in the Drawing Explorer, the layer overview briefly displayed the new layers and then got reset to show only layer 0.
SR34499, SR35307 - PDF EXPORT: when arc segments of a polyline were exported to PDF, they were represented as a chain of lines instead of arcs.
SR34651 - HATCH: fixed calculation of hatch area for boundaries containing overlapping curves.
SR34686 - DRAWORDER: was undesirably changed in a group during selection preview highlighting.
SR34711 - PRINT: some holes in solid hatches were ignored and filled.
SR34776 - 2DCONSTRAINTS: creation of constraint glyphs on drawing open can take long in drawings containing many constraints. Now glyph creation is deferred till actually required.
SR34906 - SNAP: calculation of CENTER snap for polylines is made more precise for polylines with large coordinates.
SR35036 - DISPLAY: attribute objects on layer "0", with BYLAYER color, were displayed with wrong color after one of the layers was frozen in the PS viewport (regression in V12).
SR35091 - GRIP-EDIT: when an entity was edited by grip points, it disappeared when zooming with the mouse wheel.
SR35297 - FILLET and CHAMFER: option POLYLINE gave incorrect result for polylines with non-zero global width.
SR35313 - CRASH: a crash occurred when working with a drawing containing a layer with an invalid material id.
SR35320 - RASTER ENGINE:
- white line artefacts occurred at the borders of adjacent (clipped) images.
- when zooming out images disappeared too soon.
SR35356 - SNAP: the marker size was dependent on the size of the view in perspective mode.
SR35372 - UNDO: undo chain got broken after AUDIT of blocks.
SR35415 - AUDIT: added missing linefeed in audit output.
SR35420 - DYNAMIC BLOCKS: draw order inside dynamic block got lost after editing a dynamic block property.
SR35427 - TABLE: the Table Dialog did not remain modal after opening and closing the Table Styles drawing explorer. Also improved setting Table gridlines in the Table Styles drawing explorer
SR35552 - STRETCH: failed for user-provided scenario.
SR35568, SR35764 - REFEDIT: when an entity was removed from the working set in REFEDIT session, it was no longer displayed.
SR35572 - REFEDIT: a crash occurred when executing UNDO after all entities were erased during a REFEDIT session.
SR35580 - BIGFONT DISPLAY: accuracy was insufficient.
SR35608 - SCALE LIST EDIT: on resizing the scale list edit dialog, the list of scales expands according to the available width. The entries in the list also expand according to available width. Before this fix, the entries took up only about half the width of the list and the list did not get wider when resizing the dialog.
SR35752 - LINE: construction of line tangent to two arcs has been fixed.
SR35770 - APPLICATION WINDOW SIZE: when the application window was not maximized, WNDSMAIN window size was stored in registry 1 pixel too small in both directions.
SR35775 - TOOLPALETTES: forced the display color of blocks to always use black regardless of background color.
SR35815 - REFEDIT: draworder was not saved by REFCLOSE/SAVE.
SR35822 - CHAMFER: display of chamfer angle was in radians, while it should be using the current angle format (AUNITS).
SR35834 - PEDIT: option multiple, option join: the [Jointype] keyword could not be translated in localized versions.
SR35876 - TEXTFILL: when printing an area containing clipped parts of texts, Textfill = OFF setting was ignored.
SR35921 - TABLES: could not change multiple cell values via Properties Bar.
SR35935 - EXTRUDE: operation failed for closed polylines with identical start and end points.
SR36010, SR36712 - MENU: after loading a partial cui file with MENULOAD, accelerator keyboard shortcuts no longer worked.
SR36036 - PLOT: corrected the prompt for saving changes to print settings to a layout.
SR36042 - DYNAMIC BLOCKS: when changing dynamic block parameters, block attribute visibility was not set correctly.
SR36047 - 3DFACE: option "_invisible" was rejected for the second edge, if the first edge was also defined as "invisible".
SR36163 - STRETCH: some of the line endpoints within the crossing window were not picked up by the stretch command.
SR36183, SR36206 - DISPLAY: polylines with thickness and dashed linetype were displayed with zero lineweight when viewed from the top.
SR36367 - HATCH: area calculation incorrectly gave a 0 result for a hatch contained in a user-provided drawing.
SR36462 - PRINTING: when Print settings in the Print Preview was clicked, the Page Setup dialog was opened instead of the Print dialog.
SR36496 - FOCUS: when moving the cursor over the drawing view, while working in an application window, the focus undesirably switched to the drawing view.
SR36535 - BLOCKS: the block description was not transferred when the Drawing Explorer was used to populate a toolpalette with blocks.
SR36664 - UNDO: when a drawing contained Light object(s), and _undo group/begin/end was used, a crash occurred.
SR36764 - VBA: after loading a password protected dvb project with the VBA Manager, the VBA IDE was disabled.

Applications

LISP: (setvar "HPNAME" ...) has been improved to better suppert user-type hatchpattern names.
SR34077 - BRX: negative GSmarkers < -1 of custom entities were not preserved.
SR37194 - DCL: if no cancel component was defined in a dcl dialog, the Close button in the title bar and the escape key behaved in the same way as the Ok button. From now on the Close button and the escape key will be disabled if the dcl dialog has no Cancel component.
SR37314 - DCL: a dcl file containing a non breaking space character could not be parsed. The non breaking space character (hex code "\xa0") has been added as an allowed whitespace character to our dcl parser.
SR37334, SR37446 - LISP: fixes a problem with strings stored by (vlax-ldata-xxx) functions. When drawing is saved, a wrong string encoding was used, which caused invalid (vlax-ldata) strings, when drawing is opened again.
SR37403 - LISP (read-char file): if a text file contained a 0x1A value ('EOF' character), it was not possible to read any character following after this 'EOF'.
SR37411 - LISP,SDS,BRX: during a "saveComplete" EditorReactor event, DWGPREFIX did not return the correct path of the file just saved.
SR37651 - LISP,SDS,BRX: correction for setvar("HPNAME", ".") - it is no longer rejected with an error, but instead clears the HPNAME value.

Version 12.2.16

Tue, 17 Jul 2012 18:09:37 UTC

Fixed

SETTINGS DIALOG: When opening the settings dialog in Bricscad (Linux) V12.2.15 immediately crashed. Fixed.

Version 12.2.15

Wed, 04 Jul 2012 11:05:26 UTC

New

ATI : Support for ATI graphic cards has been added to RedSDK. As a result hardware accelerated 3D rendering will now also work on ATI hardware.

Fixed

SR35093, SR34950, SR35575 - PDF: Fixed export to Pdf.
SR34839, SR34891, SR34973 - FILLET: A crash occured in FILLET command with Radius=0 when two polylines were selected. Fixed.
SR35054 - MTEXT: Fixed crash that happened when an object field was added to an mtext using the mtext editor.
SR32923 - PRINT: Print output was inappropriately shifted. Fixed.
SR35159 - CTRL+DRAGGING: When pressing and holding down the Ctrl key while dragging a selection set, the selection set is copied instead of moved when the mouse button is released.
SR34844 - INSERT DIALOG: When inserting/creating blocks or inserting raster images the dialog loading time is significantly improved for drawings containing a very large number of blocks/images.
SR34031 - EXTRUDE: Fixed EXTRUDE for 3d polylines.
SR34231 - LOCKED LAYER PROPERTIES: Fixed crash triggered by changing property values of entities on locked layers.
SR34155 - PRINT MULTIPLE COPIES: When printing to multiple copies, use one multi-copy job rather than multiple single-copy jobs. For drivers that do not support multiple copies printing, multiple jobs will still be created.
SR34281 - INSERT BLOCKS FROM DRAWING EXPLORER: Added Options dialog to Drawing Explorer, with options for insert block operation (align/scale/rotation).
SR33784 - AUTOSAVE: Filename fields were overwritten with autosave backup file name after autosave.
SR31531, SR32605 - HIGHLIGHTEFFECT: Fixed problems caused by setting HIGHLIGHTEFFECT variable to values 1 or 3 in SHADEMODE = hidden.
SR26248 - STATUS BAR: The Status Bar contains a button named 'ESnap', but the Status Bar Menu (shown when the black arrow in the right corner of the status bar is clicked) listed 'OSnap' instead of 'ESnap'. Fixed.
SR24443 - PSPACE MSPACE SWITCHING: Fixed switching from pspace to mspace, in case of not-rectangular viewport, real boundary is respected now.
SR24097 - PSPACE MSPACE: double-click in pspace doesn't lead to selecting entity in mspace.
SR34362 - INTERSECT, UNION, SUBTRACT: Corrected commands INTERSECT, UNION, SUBTRACT: if result of boolean operations is empty, then resultant entity is deleted (this concerns both 3DSOLIDs and REGIONs).
SR34362 - INTERSECT, UNION: From now on the commands UNION, INTERSECT are terminated, if less than two entities are selected, like in Acad.
SR34097 - STRETCH: Fixed stretch command, the viewport context is not scaled when stretching viewport in paper space.
SR23954, SR28339 - DRAWING EXPLORER: After erasing a block that includes references to other blocks, update the count of nested block references in the Drawing Explorer.
DRAWING EXPLORER: Fixed wrong number of block references, displayed in Drawing Explorer, in case when block has repeated items in its reference list.
ANNOALLVISIBLE: Added support for ANNOALLVISIBLE system variable, accessible through commandline and settings dialog.
SR33734 - PROPERTIES BAR: Grouped properties now show proper display name and the values as group value
SR34517 - FILEDIA: Fixed typo in the description of FILEDIA in the Settings dialog.
SR34521 - RENDER: Fixed typo in the -Render command prompt.
SR34559 - FIND: the 'zoom to' option was zooming in too closely on the text.
SR34115 - SNAP: Temporary rubber band now goes to snapped point and no longer to cursor position
SR34104 - LAYER PROPERTIES: Avoided view regeneration after changing layer properties in Drawing Explorer (thawing of layer still leads to regeneration, this is correct).
SR30320 - TABLE EXPORT: Table export is now available in the context menu when one table entity is selected.
SR34430 - HATCH: Nested hatch boundaries, produced by text entities, should be ignored in calculation of hatch area.
SR34027, SR34050 - PRINT: Fixed regression: layout graphics is shifted or even disappears from the view after printing.
SR33309 - PRINT TO FILE: Implemented 'Print to file' checkbox in the Print dialog.
RASTER IMAGES: Printing of (transparent) raster images may now work better. Your mileage may vary, depending on the printer driver, especially with PDF printers.

Application Development

SR34938 - LAYOUTSWITCHED REACTOR : Fixed a timing problem for "layoutSwitched" reactor event, which was sent much too early, when Bricscad did not have processed this internally; as result, the display system was not yet updated, which could result in strange errors and crashes, depending on client applications handling during this event.
SR35030 - LISP PLOTSTYLENAME: (vla-get-plotstylename) resp. (vlax-get-property obj 'PlotStyleName) returned a garbaged string for Layer Objects - this is fixed now.
LISP VLE: Fixed an issue with (vle-alert title msg flags) - "msg" and "title" arguments were switched
SR34995 - ENTGET: In Lisp,SDS,BRX, the functions (entget) / sds_entget() / acedEntGet() could cause an exception, when used with an AcDbBlockBegin/OdDbBlockBegin object of an erased BlockTableRecord (i.e. after _PURGE command).
SR34377 - LISP: (vl-sort) could fail and return the original (unsorted) list. This happened if the used comparator function triggered an error with (atoi) or (atof) usage, for instance with (atoi "abc") or (atof "xyz"). Fixed.
SR34417, SR34542 - LISP: Fixed 210 groupcode in (entget) function for LWPOLYLINE (was 2D by mistake, instead of 3D); now only groupcode 10 is given as 2D point for LWPOLYLINE.
SR34378 - BRX: Fixed a problem with AcApDocManager::lockDocument(kAutoWrite) - the pending document lock was not automatically released, and related Undo record was not closed.
SR34454 - LISP: corrected (setvar 'CPlotStyle ...) to match AutoCAD's (incorrect) behaviour. If PStyleMode=1, Acad does not verify the value, but simply returns input value; in this case, CPlotStyle is a read-only system variable.
SR34432 - LISP: Fixed a problem with (foreach item ), where was evaluated for each loop cycle, which could result in very strange issues (and also reduces performance).
SR34470 - LISP: A builtin Lisp functions could be reset to NIL, by using a variable with the same name as the builtin function. For safety of the Lisp engine, built-in functions are protected now.
SR34439 - LISP: When an entity is (un-)erased, do not send a "modified" event for (vlr-acdb-reactor) clients.
SR34554 - TEXTSIZE : fixed behaviour for Text/DText/Attdef commands - the TEXTSIZE system variable is now always set to last-used textsize (as assigned to text/attdef object) at the end of the commands (this matches AutoCAD behaviour), even when no dedicated textsize was set during these commands (but textsize was taken from textstyle, if non-0)
SYSVARWILLCHANGE EVENT: "sysvarWillChange" reactor event was sent too late, after the system variable was already changed; this is fixed now, "sysvarWillChange" event is correctly sent before changing the system variable
SR34419 - TEXTBOX: (textbox) / sds_testbox() / acedTextBox() - as per declaration, the text definition must be treated as origin=0,0,0 and text rotation as 0 (270 degree for vertical texts), and on world XY-plane => this is fixed now, and results are now identical to AutoCAD

Version 12.1.23

Wed, 04 Apr 2012 17:00:00 UTC

Fixed

SR31172, MDI: When trying to close the initial scratch document in on_start.lsp, briscad crashed. This was an initialization issue of the Multi Document Interface (MDI): before starting the MDI interface, a document had to be open first. This issue has been fixed by removing this constraint from the wxWidgets MDI code.
SR33995, SNAP: When snap mode was toggled inside a command, polar state was lost. Fixed.
SR27479, DWGCODEPAGE: Fixed variable DWGCODEPAGE that was 'UNDEFINED' on Linux.
SR33601: Printing commands did not run if there was no printer marked as default in the system. Fixed. HelP
LINETYPE DISPLAY: From now on dots of non-continuous linetype patterns are printed as squares, instead of thin dashes.
SR34231 LOCKED LAYER PROPERTIES: Fixed crash caused by changing property values of entities on locked layers.

Version 12.1.21

Wed, 07 Mar 2012 17:30:00 UTC

Fixed

SR25434, INSERT BLOCK: In the insert block dialog, fixed sorting of block names in the combo box. This issue was caused by a bug in wxWidgets: the wxCB_SORT style did not work properly.
SR33830, BRX: Avoid "screen update error" in client scenario, which quite often resulted in a Bricscad crash.
SR32322, SR33847, COPY PASTE: Fixed corruption of the dwg database after copy and paste operations.
PC3_APP: Added standalone pc3_app to installer.
SELECT OPTIONS: Fixed processing of options of object selection in translated versions.

Version 12.1.16

Mon, 20 Feb 2012 12:00:00 UTC

New

PLATINUM functionality has been added on linux. From now on trial keys are PLATINUM-enabled. Here is an overview of crucial differences and new features of the different license levels:
- CLASSIC
  - 2D geometric and dimensional constraints
  - Custom hatch patterns
  - Printing: import and edit page setups (decoupled from layout)
- PRO
  - All features from CLASSIC
  - Full ACIS modeling and editing
  - BRX
  - Realistic mode rendering, section planes, SECTIONPLANETOBLOCK command, visual styles
- PLATINUM
  - All features from PRO (and consequently CLASSIC)
  - Geometric 3D constraints, Design intent capturing
SCALELISTEDIT: Added command SCALELISTEDIT and dialog to allow scale list modifications in print dialog and viewport properties.
TEIGHA UPGRADE: The entire ODA dwg library has been upgraded to version 3.4.0. It has also been renamed from Dwgdirect to Teigha.
PRINT REDESIGN: Printing was thoroughly redesigned. The actual CUPS communication with the printer did not change, but the internal mechanisms to manipulate print properties were rewritten. This refactoring eases future cross-platform changes.
HATCHTOBACK: Added command HATCHTOBACK to bring all hatches to the back by changing draworder.
TEXTTOFRONT: Added command TEXTTOFRONT to bring all text and/or all dimensions to the front by changing draworder.

Fixed

BLOCK: In the BLOCK command dialog, block names are now alphabetically sorted.
DIMENSIONS:
- SR31298 - DIMANGULAR: Fixed DIMANGULAR command for DIMASSOC = 0 to have behaviour like in AutoCAD.
- SR31765, SR31767, SR31783, SR31795, SR31863, SR31865, SR31869, SR31871 - SELECTING DIMENSIONS: Fixed failure in selecting of dimensions.
- SR32188 - DIMTAD: added missing option to DIMTAD combobox in Drawing Explorer and Properties Bar (DIMTAD value 4 = "Below")
- SR32907 - ZERO DISTANCE DIMENSIONS: Fixed creation of a dimensions when the user inputs zero distance (e.g. (command "dimlinear" pt1 pt2 distance) where distance = 0).
- SR32932 - LEADER ARROW SCALING: Fixed scaling of a leader's arrow when the leader in a viewport with a scale factor different than 1 and DIMSCALE = 0.
- SR30475 - ACIS, DIMENSIONS : Added support of Acis entities in commands DIMLINEAR, DIMALIGNED, DIMANGULAR, DIMRAD, DIMDIA.
- SR33125 - SUGGEST POSITION: Fixed inappropriate suggestions to position dimensioned text and line in the commands DIMRADIUS and DIMDIAMETER commands (for DIMTIX = ON, DIMUPT = OFF).
DRAWING EXPLORER:
- TEXT STYLE PANEL: In the text style panel, an shx extension was appended after the ttf extension for TTF fonts not found on the system.
- SR19861 - LAYER PANEL: The layer states panel now shows 'old-style' layer states in grid view and in property view. They are displayed in red, and are read-only. They can be deleted.
- SR31851 - GRID VIEW: In a grid view, for some grid columns multiple selection was lost after editing a cell value.
- SR32129 - MATERIALS PANEL: The panel for editing materials had no scroll bars.
- SR30699 - SHOW XREF LAYERS: 'Show XRef Layers' is now on by default.
DYNAMIC DIMENSIONS: Fixed a small problem with the dynamic dimensions not redrawing after editing the associated text field.
PEDIT:
- SR31682 - PEDIT: Fixed PEDIT for joining of a polyline and an arc with opposite normals.
- SR32798 - JOIN: Fixed displaying the number of added segments when using the JOIN option of the PEDIT command.
- SR33205 - FIT: The option FIT of the PEDIT command inappropriately switched off linetype-mode. Fixed. The linetype-mode now remains untouched by FIT.
- SR33592 - CONVERT: Fixed an exception when question to convert into polyline was answered with "No".
- SR33593 - CONVERT CIRCLE: Converting a circle into a polyline did not create a closed polyline. Fixed.
- SR33609 - JOIN: Corrected prompt behaviour at JOIN option of the PEDIT command: when nothing is selected, it returns to previous prompt.
PRINT:
- SR31655, SR32984: Fixed: Bricscad (Linux) crashed on selecting some paper sizes in the Print dialog (e.g. "A0", "ArchE", i.e. paper sizes that are non-standard in the original Windows code).
- SR32923: Fixed wrong print output offset and scaling.
SETTINGS: Added missing system variables to Settings dialog.
SETVAR: Extended SETVAR command to make preferences available and directly editable on the commandline.
SNAP:
- EXTENSION SNAPPING: Fixed Direct Distance Entering when extension snapping is active and DYNMODE=0. Fixed extension snapping for polyline straight segments, when UCS!=WCS.
- LINE, SNAPPING: implemented deferred perpendicular snapping in command LINE.
- SR21459, SR21477, SR27509 - INTERSECTION SNAP: Plain intersection snapping behaved like extended intersection snapping. Fixed.
- SR22282 - F3: After pressing F3, current tooltip and osnap marker are undrawn.
- SR23174 - CENTER SNAP: Corrected CENTER snapping to closed polylines. The center snapping point is now placed in the center of gravity of the polygon.
- SR31776, SR31789 - DEFERRED SNAP: Changed processing of deferred tangent and perpendicular snap modes. Now they are processed with lowest priority. That is, deferred modes are deactivated if there are other snapping points.
- SR30507 - ENTITY SNAP TOOLBAR: Added icon for "midpoint between 2 points" (mtp, m2p) to the entity snap toolbar.
- SR31962 - RECTANGULAR SNAP: Fixed ORTHO for the rectangular snapping to have possibility to snap to the Z axis.
TABLES: Adding Tables using the table dialog now works correctly.
UCS:
- SR30971 - POLYGON: Fixed problem with UCS in Polygon command.
- SR32367 - MODELSPACE/PAPERSPACE: Fixed wrong transformation of entities, being copied in paper space, in case if modelspace UCS is changed.
- SR32545 - LASTPOINT: The command "_UCS _3points" did not reset LASTPOINT system variable to (0,0,0) - this is now fixed.
SR23446 - SECTION: Fixed an issue with "section" objects. Before this fix, the region did not get current entity properties (layer, color etc.).
SR23453 - LAYER: Using the layer command or (setvar "clayer" ...) it was possible to make a frozen or xref-dependent layer the current one. Fixed.
SR24266, SR29573, SR30349, SR30547, SR30763 - CUSTOMIZE: Fixed a problem in the customize dialog. An error message was displayed when attempting to create a partial CUI file from the customize dialog.
SR25923, SR28810, SR32875, SR33059 - PASTE AS BLOCK: implemented paste as block in Bricscad (Linux).
SR28484, SR29293, SR30324 - GRIP EDIT: Fixed grip edit for arc segments of a polyline. Fixed grip edit for spline fitted polyline. Fixed grip edit for multiple grips in a solid.
SR28800 - EDIT REFERENCE: Fixed crash on attempt to edit a reference that has mutual dependency on another reference.
SR28870 - PARENT FOLDER: it's now possible to use ".." in meaning "parent folder" for Bricscad argument (e.g. $ bricscad ../test.dwg)
SR29059 - XDATA: XData (EED, Extended Entity Data) now gets copied to all parts of a trimmed entity.
SR29128 - SLICE: Adapted the SLICE command to check for destination layer. Before this fix, when using the option BOTH of the SLICE command, one of the sliced solids was created in layer 0 instead of in the original solid's layer.
SR29391 - SHX: Leading whitespace in some shx fonts was absent in Bricscad, which caused some mtexts to wrap on two lines in acad but not in Bricscad.
SR29412 - PLINE: Fixed PLINE to avoid construction of a multiple polylines instead of a single polyline.
SR29641, SR32973 - TTF QUALITY: Improved text rendering on Linux. Now TEXTQLTY variable is used in the following manner:
- TEXTQLTY < 49: old rendering method is used. The actual value is not used.
- 50 <= TEXTQLTY <= 100: new approximation algorithm for Bezier curves. Greater values imply better quality but more points for the approximating polyline so performance-wise a lower value is recommended.
- TEXTQLTY = 50 is the default value
SR30133, SR32326 - MATCHPROP:
- An empty selection no longer breaks the command loop.
- Properties are now copied immediately after choosing target entity.
- Fixed selection behavior of MATCHPROP for target entities (restored multiple entities selection possibility)
SR30186 - FIND AND REPLACE: It was possible to enter custom text in the "Search in" dropdown control of the Find and Replace dialog. This did not make sense. The control is now read-only.
SR30291 - ATTRIBUTE EDIT DIALOG: In the Attribute Editor dialog, while inserting a field, bricscad crashed when selecting an object. Fixed.
SR30432 - HATCH, GRADIENT: The Hatch and Gradient dialog has 3 island detection types: Nested, Outer and Ignore. The same island detection types appear in the Properties bar as: Normal, Outer and Ignore. Changed 'Normal' to 'Nested' in the Properties bar.
SR30487 - SELECTION SETS: An empty entity selection (by user or by application) did clear an existing (non-empty) selection. This caused (ssget "_P") or _SELECT _P command to fail. Fixed.
SR30503: Fixed block redefinition issues.
SR30569 - PATH EXTRUDE CIRCLE: Circle couldn't be extruded along path, since path belonged to the group.
SR30598 - DYNAMIC DIMENSIONS: Space bar in input fields of dynamic dimensions is now treated the same way as Enter.
SR30698 - AREA: The AREA command now accepts hatch entities as well.
SR30757 - HATCH: Fixed using options SELECT, PREVIOUS in the HATCH command to use the previous selection set.
SR30844 - CIRCLE GRIP POINTS: Fixed circle grip points.
SR30948 - STATUSBAR: Fixed: Changing the status of a system variable by clicking on a statusbar label during lisp execution (pause) now works.
SR31013, SR33407 - PASTE: During PASTE command, ORTHO mode was mistakenly respected. Fixed.
SR31040, SR31470 - SEPARATE SOLID: Improved SOLIDEDIT -> Body -> seParate to place the separated bodies to the current layer instead of the default layer.
SR31409 - BREAK: Fixed BREAK for a line when a user picks two identical points which are not on this line. Previously the line incorrectly disappeared.
SR31436 - DWF: Fixed a crash on export to DWF 3D v6.1 format
SR31449 - BLOCK SCALING: Fixed block scaling if the scale value is changed with Properties panel.
SR31479 - OFFSET: More descriptive error messages are shown for failing offset commands.
SR31580 - HIDDEN MODE LINEWEIGHTS: implemented support of lineweights in Hidden render mode.
SR31748, SR32691 - TRIM: Fixed TRIM command for closed polylines and xlines.
SR32003 - ICONS: Improved icons for dclinear, gcfix, gcequal and dcconvert.
SR32155 - COMMANDLINE: If the bricscad commandline contained only a prompt, backspace inappropiately moved the cursor forward. Fixed.
SR32217, SR32487 - EATTEDIT: It was impossible to save a drawing after inserting a field via EATTEDIT dialog.
SR32288 - PASTEBLOCK: Fixed "Key not found" failure during PASTEBLOCK command.
SR32356 - SETTINGS: Fixed a problem when editing folder list properties (e.g. SRCHPATH) in Settings dialog. After a new value had been entered, if the editor's dialog was relaunched, the old value was kept.
SR32628, SR31470 - SOLID, SEPARATE: Solidedit>body>separate always lost one of the disjoint solids.
SR32663 - HATCH: fixed copying hatch properties (angle) in BHATCH dialog
SR32715 - VIEWPORT SIZE: Changed the size of the viewport that is created while activating a new paper space layout. It is now proportional to the printable area with scale 0.8.
SR33456 - DYNAMIC BLOCK PROPERTIES: Fixed a problem with properties of Dynamic Blocks not being shown in the Properties Bar.
SR33540 - DELETE: Fixed a problem where pressing DELETE key was handled at main window level instead of the focused text control.

Application Development

ACADVER: Increased ACADVER to 18.0.
LISP: Fixed a bug in (member item lst) and (vl-position item lst) - using 'item' of type VLA-Object, VARIANT, SAFEARRAY failed, when searching them in a list 'lst'.
LISP/SDS: Performance improvements for entdel, entmake, entmakex.
SR17936, SR25582, SR27079, SR27793, SR29561 - XDATA REFERENCE UPDATES: Fixed problems with incorrectly updated extended entity data (XDATA, EED) reference points (1011, 1013, 1041, 1042) after several operations like STRETCH and GRIP_STRETCH.
SR25805 - MENU CUSTOMIZATION: (menucmd "Ggroup.id=~") did not work for submenus. Fixed.
SR32664 - LISP/SDS/BRX : ssget("X" filter) failed to select entities using XData group code specifications, example : (ssget "X" (list (list -3 (list "APPID" (cons 1005 "323")))))); this is fixed now
SR32822 - LISP: Fixed a problem with (defun-q) and (defun-q-list-ref) : these functions worked with all functions, defined by (defun), but should only accept functions defined by (defun-q).
SR33420 - LISP VLAX-GET: The function (vlax-get) did not "explode" non-native objects like Variants and SafeArray recursively. Fixed.
SR33509 - LISP DCL CASE SENSITIVITY : fixes a problem with DCL tile keys - by mistake, the tile keys were treated as case-insensitive, but should be handled case-sensitive; this is fixed now

RedSDK system requirements

Bricscad's non-wireframe GPU-accelerated render modes are based on RedSDK technology from Redway3D®. These render modes require a supported GPU (graphic processing unit, graphic card).

NVIDIA graphic cards are supported. It is advised to use the latest recommended driver from NVIDIA.
ATI cards are not yet supported. Although ATI cards may work, at this point NVIDIA cards have been targeted.
It is currently not possible to install a NVIDIA or ATI driver on a laptop with dual graphics. As a result, RedSDK on linux is not supported on laptops with an INTEL Core i3, i5 or i7. This is due to a limit in the X server implementation that is not capable of handling several display adapters. This restriction is not specific to RedSDK. There is no solution possible on our side.
INTEL cards are not supported. Drivers for INTEL cards are normally pre-installed with the Linux distribution, but they typically don't include any 3D acceleration.

More detailed driver recommendations are in preparation.

Please use the Support Request pages at www.bricsys.com to report problems.

Version 11.3.16

Tue, 21 Jun 2011 18:00:00 UTC

Fixed

TRIM: In version 11.3.15, selection of cutting entities in the TRIM command was broken. This was caused by new code for selection preview and cycling for block subentities. Fixed.
PRINT PREVIEW: Sometimes print preview for configuration "None (uses Default)" did not work although default.pc3 file was generated and although preview did work for any other print configuration. This was caused by a path issue: plain pc3 files were identified by their full path whereas default.pc3 was identified by its file name only. Fixed by identifying default.pc3 by full path as well.

Version 11.3.15

Thu, 16 Jun 2011 16:05:00 UTC

New

SR25999, SR28841, SR29121, SR26569, SR29770 - SVG EXPORT: Added SVG export.
MDI: Ctrl-Tab/Ctrl-Shift-Tab now can be used to switch to next/previous document, the same as when using WNEXT/WPREV commands.

Fixed

SR29565, SR29578 - MDI/MENU/LISP: Fixed a crash in the multi document infterface (MDI) when using partial CUI files and menu Lisp files.
SR23408 - TEMPLATE ON STARTUP: Added startup option -t to specify a template drawing. When invoking Bricscad (Linux) from an operating system terminal, use the syntax "bricscad -t template.dwg".
SR25702, SR26772 - LIMITS BY MENU: The menu item Settings>Drawing Limits could only toggle limits on/off, it could not be used to set the limit corners. Fixed.
SR29604, SR25960, SR28914 - STATUS BAR: On right clicking status bar items, the context menu for toggling toolbars was displayed. Fixed.
SR29686 - UNICODE FILENAMES: When using non-ASCII characters in filenames (á, é, ã, etc...) saving failed, saying that the file is locked and marked as read-only. This issue occured in version 11.3.8 and was caused by the new locking functionality. Fixed.
SINGLETON: Implemented single instance support for Linux. Accessible from the Settings dialog, search for the variable "SINGLETON".
LISP/SDS/BRX API:
- SR30045 - SELECTION FILTER: Fixed a potential endless loop ("hangup"), when a selection filter is used with specific DXF groupcode, which appears multiple times in (entget) list, like for groupcodes 10, 100 etc...
- SR30045 - TRUECOLOR SELECTION FILTER: Fixed an issue with selection using truecolor filter (dxf code 420).
- SR30137 - FENCE: Corrected fence selection mode (_F) for ssget. Before this fix, the last fence point was ignored if the last and first fence point were the same.
- SR28891 - INPUTCONTEXTREACTOR: Fixed a crash in InputContextReactor.
- SR29274 - LISP/SDS FILE DIALOG: In the file dialog that is shown in response to (getfiled) or sds_getfiled(), two extension issues were fixed.
  - The selection wildcard for "All Files" has been changed from "*.*" to "*". The demand for filenames to have an extension is customary on windows, not on linux.
  - The selected file extension was not added to the default filename. Fixed.
- SR29274 - BRX ENTRYPOINT: The events ::kQuitMsg and ::kPreQuitMsg were missing in acrxEntryPoint(). Fixed.

Version 11.3.8

Wed, 27 Apr 2011 10:10:00 UTC

New

MDI: Further improvements have been added to the MDI or Multi Document Interface of Bricscad (Linux), which was redesigned in 11.3.5.
- The order of appearance of the document tabs can now be manipulated by drag-and-drop.
- Added Next and Previous button to the Window menu for document navigation.
- Added context menu to the document tabs.
- Added means to customize the document tabs from the Settings menu, in the new category "Settings>Program options>Display>Document Tabs".
APPLOAD: The APPLOAD dialog now shows and loads BRX Linux modules.
OPEN: From now on drawings that are opened will be locked. This avoids simultaneous edits to one drawing.

Fixed

SR29018, SR28960, SR26326, SR29040 - HATCH: Exploded hatches no longer cause problems for hatch boundary detection.
SR29115 - ACIS: (entget(car(entsel))) crashed when selecting an ACIS object. Fixed.
SR29170 - DRAWING EXPLORER: Fixed exception when generating a list of layers in the Drawing Explorer.
TOOLBAR CONTEXT MENU: The checkboxes in the toolbar context menu acted on the wrong gui item. For instance, clicking on "Command bar" could toggle the properties bar.
ZOOM: Fixed a bug that appeared in version 11.3.5. Zooming to extents was calculated relatively to the initial size of the main graphics window rather than its current size.
SR26108, SR26238, SR29282 - PRINTING: Fixed printing to Arch paper sizes. Before this fix, setting paper size to either ArchC, ArchD or ArchE resulted in Bricscad(Linux) actually using ANSI C, ANSI D or ANSI E sizes instead.
BOOLEAN ENTITY DATA: When using any API to create an entity, creating records with groupcode 290 for boolean data failed. This happened for instance in lisp when using entmakex for creating XRecord data. Fixed.
SR29375 - OFFSET: Taking an offset of a polyline did not preserve "linetype generation" and "global width" properties. Fixed.
SR29418 - DCL: When using fill_image over the entire area of a dcl image, all previously drawn objects (slides, vectors, fills) are erased from memory to avoid needless redrawing. However, this also erased a label that was added to the image using set_tile. A label is to be displayed on top of all other content, so fill_image must not erase the label. Fixed.
SR29417 - DYNAMIC BLOCKS: In Bricscad (Linux) dynamic blocks could not be edited from the properties panel. Fixed.
BRX SDK: Various fixes for BRX usage on linux were added, for instance:
- Solved a circular dependency between AcDbHandle and AcDbObjectId, which GCC was not able to resolve. VC8 never had this problem thanks to lazy evaluation.
- Solved timing issues related to global/static objects initialisation.
LISP: Fixed a few regressions that appeared in V11.1 or V11.2:
- SR29283: Pushing ESCAPE key during (command ... PAUSE ...) sequence failed to stop lisp execution.
- SR29382: Using embedded (getvar) inside (command) sequences was broken.

Version 11.3.5

Tue, 05 Apr 2011 12:05:00 UTC

New

ACIS 3D ENGINE: Bricscad (Linux) now includes the ACIS 3D engine. You need a PRO-enabled license key for full ACIS usage. Bricscad (Linux) PRO licenses are not yet available in our E-store, but new V11.3.3 trial keys are PRO-enabled. If you already used a V11 trial key, contact support to request a new PRO-enabled trial key. ACIS viewing works with any license key.
SOLPROF: The SOLPROF command has been added. This command uses the ACIS 3D engine for hidden line removal. It can be used in layout space in a model space viewport.
BRX SDK: From now on the BRX SDK is available for Bricscad (Linux). The BRX SDK consists of:
- a set of code compatible C++ headers
- the necessary libraries to link against
- documentation
The BRX SDK is not installed with Bricscad itself, but is distributed through a separate download source. You can get free access to the BRX SDK, simply by registering yourself as an application developer on the Bricsys website (www.bricsys.com). During registration, mark the check box for "ARX/BRX/DRX", and you will receive the necessary information to get started.
- Features of the BRX (Linux) SDK
  - More than 90% of BRX (Windows) functionality is also available on Linux.
  - BModeler, Hidden Line Removal and BRep APIs are also included (ongoing development)
  - The BRX (Linux) SDK includes a "Windows Platform Emulation" layer which allows to use Windows-based developer source code to be used under Linux. The Windows Platform Emulation layer includes a wide range of functions, classes and interfaces from
- Features not available in the BRX (Linux) SDK
  - MFC based user interface extensions: AcUi and AdUi categories
  - COM interfaces callable from C++.
  - very few undocumented and global functions, which directly use MFC UserInterface classes (like CWnd, CMainFrame etc.) are not available
PC3 EDITOR: for editing Printer/Plotter configurations.
LINE TYPES:
- BATTING, Batting SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
- FENCELINE1, Fenceline circle -0-----0----0-----0----0-----0----
- FENCELINE2, Fenceline square -[]-----[]----[]-----[]----[]----
- TRACKS, Tracks -|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-
- ZIGZAG, Zig zag /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
SR28706 - GRIDAXISCOLOR: Added support for GRIDAXISCOLOR.

Fixed

FILLET:
- SR27663: Fixed FILLET for polylines with non-zero widths (filleting of two polylines).
- SR28180: Fixed FILLET for lines and arcs with large coordinates.
- SR28478: Fixed FILLET for two polylines with large coordinates.
PEDIT:
- SR24963, SR26982, SR27382: Fixed joining two polylines, joining a polyline with a line, joining a polyline with an arc, conversion of a line to a polyline.
- SR25436, SR26935: When running "Insert new vertex" on 2d polylines, the "X" sign that marks the current vertex did not move to the inserted vertex. Fixed. Fixed joining an empty selection set.
- SR27881: A closed polyline created from a series of connected lines using the JOIN option of the PEDIT command was not recognized by the CENTER entity snap when PLINETYPE > 0. Fixed.
MTEXT:
- SR27318: Rewritten code for zooming to mtext when mtext editor is started.
- SR27318: Fixed using mouse with mtext editor in perspective mode.
- SR27318: MTEXT editor dialog is moved if it hides the caret.
- SR28527: MTEXT editor selects word on double click.
- SR28527: Ctrl-W shortcut selects current word in the MTEXT editor.
- Fixed caret angle for oblique text.
DCL:
- SR24680 - TEXT LAYOUTING: During layouting, any dcl component receives additional width proportional to the size of its label attribute. This was calculated using the number of characters and an average character width. This was inappropriate for text items with many spaces. Fixed by using the actual text extents during calculation.
- SR24680, SR26889 - COMPLEX DCL LAYOUTS: Avoid too large dcl dialogs in complex layouts. Bricscad uses wxWidgets box sizers to layout components in a dcl dialog. A plain wxBoxSizer sometimes rounds up the minimum size of a component to obey proportions according to exact integer ratio's. However, in complex layouts this can considerably enlarge the entire dialog. Indeed, this rounding can accumulate on multiple levels. This has been fixed by introducing a special purpose box sizer which does not round up minimum sizes.
- SR26889 - ATTRIBUTE WARNINGS: When an attribute has an inherited value and that value is modified in a derived definition, a warning used to be displayed. For instance, a button has the built-in attribute "is_tab_stop=true". On defining a button with "is_tab_stop=false", a warning was given. The attribute-warning mechanism has been made more sensitive. From now on, a warning for inherited attributes will be given only if the derived definition repeats the same value again. If an attribute is specified more than once within the same scope, a warning will be given as well. Mind that these warnings are only given if the audit_level has been set to 3 by means of this definition: "dcl_settings : default_dcl_settings { audit_level = 3; }".
- SR26860, COLUMN ALIGNMENT: alignment=top, aligment=bottom did not work in a column.
SR28397, 28589 - DRAWING EXPLORER: Some strings were not translatable.
- string 'Overwrite this layer state' in Layer States Explorer
- panel names 'Open Drawings', 'Drawings', 'Details' and 'Preview'
- 'Views' panel, 'Background' column: The strings in the Background combo box were not translatable.
SR27855, SHELL COMMANDS: The default shell command aliases have been changed to relevant linux commands. Before this change, irrelevant windows-only shell commands were preset. The shell command aliases can be accessed from the menu "Tools>Customize>Shell Commands".
STATUSBAR: The info widget at the lower left of the main window (in the status bar) is too small for all but the smallest hints. Fixed by assigning all leftover space to this widget.
SR28955 - PDF EXPORT: Enabled PDF export of a truetype fonts in linux.
MDI - The MDI or Multi Document Interface of Bricscad (Linux) has been redesigned. As an immediate result, close buttons for closing drawings in one click are now displayed. On longer term, this makes it possible to implement some other requested MDI-related features, like for instance making the display of document tabs optional.
SR26893 - CURVE/SPLINE FIT POLYLINES: Fixed display and editing by means of the properties bar.
SR27979 - GROUP: The keyword "UN-GROUP" has been replaced with the "EXPLODE" for compatibility with AutoCAD. The keyword "UN-GROUP" is preserved as hidden.
SR26423 - ATTEXT: The dialog version of this command erased the template file, resulting in empty output. Indeed, an internal check of the accessibility of the template file used a non-existing flag (option). In our windows version, this non-existing flag happened to be harmless. On linux this flag happened to erase the contents of the accessed file. Fixed.
SR28512 - BREAK: Implemented BREAK command for splines.
UCS: 'MOVE' option is no longer hidden.
SR22613 - TEMPORARY FILES: The default filemode for temporary files has been changed from 777 to 666.
UNT FILES: Fixed reading unit conversion files *.unt. This was broken by windows/linux line endings incompatibility.
SR28671 - ARC: Start points and end points with a negative angle were always specified in degrees. Fixed.
REGISTRY EMULATION ON LINUX: Fixed import/export of *.reg files.
SR27368 - BITWISE MASK OPERATOR: The relational operator "&=" (Bitwise masked equals) does not work in selection set filter lists in lisp commands.
SR18617, SR22799 - QUICKSELECT: When working in modelspace on a layout tab, the quickselect tool now considers entities in modelspace, not paperspace.
CENTER POINT CALCULATION: The selection set of entities visible in the current view now is made using Window-Inside selection instead of Window-Crossing. Before this change partially visible large entities undesirably influenced the center point.
SR27164 - OSNAP: Extension and parallel entity snaps were missing in the OSNAP command options, both at the command prompt and in the prompt menu.
SR26226 - DIMORDINATE: While working in paper space, DIMORDINATE was cancelled when snapping to a model space entity.
SR25937 - ATTEXT: The option "All" of ATTEXT should extract attributes from all layouts and not only from active one. Fixed.
SR24133 - ZOOM: "X_P" was interpreted as "X" instead of "XP".

SR28706 - GRIDAXISCOLOR: Added support for GRIDAXISCOLOR.

Fixed

FILLET:
- SR27663: Fixed FILLET for polylines with non-zero widths (filleting of two polylines).
- SR28180: Fixed FILLET for lines and arcs with large coordinates.
- SR28478: Fixed FILLET for two polylines with large coordinates.
PEDIT:
- SR24963, SR26982, SR27382: Fixed joining two polylines, joining a polyline with a line, joining a polyline with an arc, conversion of a line to a polyline.
- SR25436, SR26935: When running "Insert new vertex" on 2d polylines, the "X" sign that marks the current vertex did not move to the inserted vertex. Fixed. Fixed joining an empty selection set.
- SR27881: A closed polyline created from a series of connected lines using the JOIN option of the PEDIT command was not recognized by the CENTER entity snap when PLINETYPE > 0. Fixed.
MTEXT:
- SR27318: Rewritten code for zooming to mtext when mtext editor is started.
- SR27318: Fixed using mouse with mtext editor in perspective mode.
- SR27318: MTEXT editor dialog is moved if it hides the caret.
- SR28527: MTEXT editor selects word on double click.
- SR28527: Ctrl-W shortcut selects current word in the MTEXT editor.
- Fixed caret angle for oblique text.
DCL:
- SR24680 - TEXT LAYOUTING: During layouting, any dcl component receives additional width proportional to the size of its label attribute. This was calculated using the number of characters and an average character width. This was inappropriate for text items with many spaces. Fixed by using the actual text extents during calculation.
- SR24680, SR26889 - COMPLEX DCL LAYOUTS: Avoid too large dcl dialogs in complex layouts. Bricscad uses wxWidgets box sizers to layout components in a dcl dialog. A plain wxBoxSizer sometimes rounds up the minimum size of a component to obey proportions according to exact integer ratio's. However, in complex layouts this can considerably enlarge the entire dialog. Indeed, this rounding can accumulate on multiple levels. This has been fixed by introducing a special purpose box sizer which does not round up minimum sizes.
- SR26889 - ATTRIBUTE WARNINGS: When an attribute has an inherited value and that value is modified in a derived definition, a warning used to be displayed. For instance, a button has the built-in attribute "is_tab_stop=true". On defining a button with "is_tab_stop=false", a warning was given. The attribute-warning mechanism has been made more sensitive. From now on, a warning for inherited attributes will be given only if the derived definition repeats the same value again. If an attribute is specified more than once within the same scope, a warning will be given as well. Mind that these warnings are only given if the audit_level has been set to 3 by means of this definition: "dcl_settings : default_dcl_settings { audit_level = 3; }".
- SR26860, COLUMN ALIGNMENT: alignment=top, aligment=bottom did not work in a column.
SR28397, 28589 - DRAWING EXPLORER: Some strings were not translatable.
- string 'Overwrite this layer state' in Layer States Explorer
- panel names 'Open Drawings', 'Drawings', 'Details' and 'Preview'
- 'Views' panel, 'Background' column: The strings in the Background combo box were not translatable.
SR26893 - CURVE/SPLINE FIT POLYLINES: Fixed display and editing by means of the properties bar.
SR27979 - GROUP: The keyword "UN-GROUP" has been replaced with the "EXPLODE" for compatibility with AutoCAD. The keyword "UN-GROUP" is preserved as hidden.

Version 11.1.19

Fri, 04 Feb 2011 10:50:00 UTC

Fixed

SR27633, SR25614 - The setting "Ignore all but first bit of DBMOD for close" is now supported on Linux. This variable is accessible in the settings dialog, section "Program options", "Open and save".
SR28067 - Re-implemented and improved registry emulation on linux.
The lisp functions vl-registry-read and vl-registry-write were temporarily removed because of a design flaw. All configuration settings of bricscad are saved in the file ~/.bricscad/config on closing bricscad. The registry values were saved in the same file. However, on closing bricscad saving the configuration settings would overwrite the entire file, including any custom registry modifications. So, vl-registry-read and vl-registry-write could only work within the same bricscad session.
The lisp functions vl-registry-read and vl-registry-write are reintroduced. In the new implementation the file ~/.bricscad/reg is used for registry values instead of ~/.bricscad/config. Also, the file /opt/.bricscad/reg has been introduced for registry keys that should be accessible by all users (eg in HKLM).
SR27758 - Fix for translated versions: The words "Next" and "Previous" were not translated in some options of the command "PEDIT".
SR22874 - Respect umask setting while saving .dwg files with Bricscad (Linux).
SR25909 - Profile manager: Before the User Profile Manager dialog opens, save the current settings to make sure up-to-date settings will be used in 'Export' and 'Copy' functions.
SR26424, SR26764 - The main menu was not displayed on startup. The wxGtk menu initialization was not finished by the time the contents of the menu were provided. Fixed by waiting for all pending wxWidgets operations to finish before providing the menu contents.
DCL:
- SR27237: In a dcl list_box on linux, the text height was a lot smaller than the row height. The height of text was set in a windows-specific way. Fixed.
- In a dcl list_box with the attribute fixed_width_font, the used font on linux was not a fixed width font. The system was searched for an ANSI font that exists on windows only. On not finding the font, a variable width font was selected by wxGtk instead. Fixed by querying the system for another fixed-width font if the first selected font is variable width.

Version 11.1.18 BETA

Version 11.1.17

Wed, 08 Dec 2010 11:05:00 UTC

Fixed

SR27230 - MOUSE CLICK CUSTOMIZATION: Fixed customization of control-right-click.
DYNAMIC INPUT and DYNAMIC DIMENSIONS:
- SR26978, SR27022, SR27349, SR27359, SR27352, SR27383: fixed a crash.
- Fixed using the mouse wheel for zooming while editing a dynamic dimension input field.
DRAWING EXPLORER: The toolbar in Data Panel and Editor Panel now always takes up the entire width of the panel. Before this change, some toolbar icons were not visible.

Version 11.1.16

Tue, 30 Nov 2010 11:43:00 UTC

New

PDF EXPORT: Added PDF export on Linux.
DYNAMIC INPUT and DYNAMIC DIMENSIONS:
- DYNMODE variable: controls whether dynamic dimensions are available while creating/editing entities.
- DYNMODE can be switched ON/OFF using the new DYNMODE button on the status bar.
- DYNDIVIS variable: specifies how many dynamic dimensions are displayed simultaneously.
- DYNDIGRIP variable: specifies which dynamic dimension types are displayed.
- DynDimColorHover setting: specifies the color of dynamic dimensions when hovering over a grip point.
- DynDimColorHot setting: specifies the color of dynamic dimensions when moving grip points.
- DynDimLineType setting: specifies the line type of dynamic dimensions when moving grip points.
- DynDimDistance setting: specifies a factor for the distance between the dynamic dimensions line and the grip points being dimensioned.
DYNAMIC BLOCKS: insertion of dynamic blocks and modification of properties through the properties bar have been implemented, so existing dynamic block libraries can be leveraged.
SELECTIONAREA, WINDOWAREACOLOR, CROSSINGAREACOLOR and SELECTIONAREAOPACITY variables control whether, and how, the selection area is visualized.
MIDPOINT SNAP: the MTP (midpoint-between-two-points) command modifier can be used at any Command prompt to locate a point by keying in MTP or M2P.
PARALLEL SNAP: constrains a line, polyline segment, ray or xline to be parallel to another linear entity.
PARALLEL command: toggles the parallel snap setting.
PERFORMANCE:
- CACHELAYOUT setting: controls whether the content of layouts is cached, making layout switching up to 10 times faster. Caching requires extra memory, but while implementing the cache mechanism we could reduce the memory needed to display entities. The net result is that the memory needed to display drawings has been reduced, even when layout caching is activated.
HPSEPARATE: the hatch dialog now offers the possibility to create separate hatches when clicking subsequent points to detect and create hatch boundaries.
MTEXT: added support for background masks.
CREATEVIEWPORTS variable: controls if a new viewport is created for newly created layouts.

Fixed

SR26679 - XDATA: Fixed storing of extended entity data (EED or XData) and fixed layouting of extended entity data dialog.
SR2552, SR25515, SR25759, SR26131, SR26297, SR26339 - DISPLAY: Added settings variables HIGHLIGHTEFFECT and HIGHLIGHTCOLOR. These variables can be used to customize selection highlighting, the visual appearance of selected objects. This provides a workaround for a display problem with some older ATI cards (using Mesa drivers). On computers suffering from this problem only the grip points of selected objects were visible.
TRANSLATED VERSIONS: Some standard labels like "OK", "Cancel"... were not translated. More precisely so called "stock items" in wxGtk did not get translated. It seems the translation string field "msgctxt" prevents gtk from finding translations of stock items. Where possible, Bricscad (Linux) uses its own translations instead.
SR27266 - SDS: Added sds headers in folder API/sds next to the bricscad executable file.
SR26424 - MENU LOADING: Added optional menu diagnostics. If menu diagnostics are enabled, messages will be displayed describing the success or failure of some stages of the menu loading process. This option can be controlled by means of the system variable QAFLAGS. The 15th bit of QAFLAGS represents the enabled state of menu diagnostics. Add 2^14 = 16384 to QAFLAGS to enable menu diagnostics.
FOCUS: When Bricscad (Linux) has no focus, set the focus on the commandline. Before this fix, in many situations Bricscad (Linux) had no focus. The Bricscad source code assumes a focus will always be set automatically, but apparently this is not true on gtk.
AUTOSAVE: Autosave, Save on crash and Save all now work as expected.
LISP
- SR19622: Fixed a problem with (read-line) with UTF encoded files. Srings read by (read-line) function from UTF encoded files were stored with the physical length as stored in file, instead of using the logical length of the strings - in result, such strings were shown with trailing \000 characters at command line, and (strlen) returned physical length.
- SR19625: Fixed a problem with (vlax-xxx) functions dealing with SAFEARRAY data type. Before this fix, storing and retrieving strings with SAFEARRAY could result in memory corruption and Lisp engine crash (segmentation fault).
- SR19666, SAFEARRAY with VARIANT objects: SafeArrayGetElement() and SafeArrayPutElement() did not correctly store and retrieve VARIANT objects.
- SR19668: Fixed problems when writing to file. Mixed ANSI and UNICODE content could be written to the same file.
- SR19686: Fixed a bug using ESCAPE key while DCL dialog was active. This issue could cause unhandled exceptions.
- SR19760: Added support of home folder alias tilde "~" for file handling functions. Before this fix using the tilde "~" character for user home folder did not work with Lisp file functions like (findfile "~/name.lsp"), (load "~/name.lsp") and similar.
- SR19763: Fixed (vl-string->list) behaviour. As opposed to the (ascii) function, (vl-string->list) did not convert the characters to system ANSI codepage.
ACADVER was increased to 17.2
SR17381 - CUI: when the user did not have write access to the main CUI file, attempts to save the file caused an 'application became unstable' alert. Now, a more appropriate message is shown.
SR22272 - TIME variables: when creating a new drawing from a template, the time variables were taken from the template drawing. This has been corrected:
- TDCREATE, TDUPDATE, TDUCREATE, TDUUPDATE are set to the current time.
- TDINDWG and TDUSRTIMER are reset to zero.
SR26014 - XDATA: introduced copying of xdata when dimstyle was modified.
SR26365 - MTEXT EDITOR:
- Error occurred when editing mtext residing at YZ-plane, viewed from the X direction.
- The Width adjustment box now has a fixed size of 30x20 pixels, instead of a size relative to the mtext's text height.
SR26445 - LAYOUT SWITCH: if caching of layouts is active (CACHELAYOUT = On), entities on viewport-frozen layers could be missing from the display when switching to other layouts.
MTEXT: improved justification of MTEXT and multiple and single line attributes.
SHADEMODE: highlighted edges were not visible because only faces were drawn.
VIEWPORTS: frame of active PS viewport should be visible even if the viewport is on frozen or off layer.
SR16102 - LIST: 1. Multiple blank lines were eliminated in SORT modes. 2. Text screen flickering while switching to Sort/Sequential mode has been avoided.
SR16373 - LIST command: added support for MLEADER entities.
SR16506 - HATCH: hatches were invisible eventhough their number of dashes was still far below the MAXHATCH threshold.
SR19167 - HATCH: the definition of the GRAVEL1 hatch pattern was corrected.
SR19600, SR20185, SR26202 - AUDIT, RECOVER: fixed for drawings with duplicate entries in symbol table.
SR19972, SR21418, SR24232: WBLOCK ALL incorrectly handled paperspace entities.
SR23747 - PICKSTYLE: added support for associative hatches when PICKSTYLE=2.
SR23766 - DRAWORDER: command did not allow to select entities on locked layers.
SR23884 - DISPLAY: during loading, the multiline attribute position was shifted for certain fonts.
SR24068 - SNAP MARKER: if snapping was explicitly activated during ZOOM command, snap markers were not drawn.
SR24109 - DIMSCALE: leader text had zero-height if DIMSCALE was 0.
SR24353, SR24885 - VIEW RESTORE: should restore view in active viewport instead of whole model space.
SR24435 - TEXT: text in user-provided drawing was shown in the wrong location on open.
SR24511 - MATCHPROP: behavior was not compatible if entities were preselected.
SR24618 - SNAP: fixed snapping to SPLINE.
SR24666 - PEDIT: snap was not working during EDIT stage.
SR24708 - MTEXT EDITOR: when using a locale different from Us_EN, formatting double precision numbers intermittently failed.
SR24732 - DRAWING EXPLORER: incorrect number of block references is reported in Drawing Explorer for copied blocks
SR24859 - INSERT: Drawings that contain an AcDbTextStyleRecord with empty name field (name is "") could not be inserted into another one.
SR24890, SR26055 - MULTIPLE: failed to repeat commands entered as global name with underscore in localized versions (e.g. _MULTIPLE _CIRCLE).
SR24987 - OPEN: drawing could not be opened because it contained a NULL block. Solved by erasing the erronuous block.
SR25073 - SAVE: user-provided drawing could not be saved in dwg2010 format.
SR25079, SR25153 - CIRCLE TTR: fixed construction of a circle tangent to a closed polyline using TTR mode (Tangent-Tangent-Radius).
SR25132 - CMDACTIVE variable:was not set to 1 if a system variable was being changed directly by typing its name.
SR25158 - CHAMFER: failed for two lines located at large coordinates.
SR25324 - HATCH: fixed crash when trying to detect a boundary in an area consisting of many parallel line segments.
SR25336 - EXTENTS: extents of block references should not include extents of invisible attributes.
SR25432 - ATTEXT: fixed wrong cyclic reference detection while extracting attributes from nested blocks.
SR25448 - GRIP EDIT: allowed to edit entities on locked layers.
SR25461 - COORDINATE DISPLAY: the coordinate display mode was not reset after canceling the POLYLINE command.
SR25532 - MTEXT EDITOR: applied incorrect text justification.
SR25712 - INSERT: fixed a crash on insertion of uniform scaling block, also 'Insert' dialog behavior was corrected for uniforml scaled blocks.
SR25807 - TRIM: when an insert was selected before starting the command, a crash occurred.
SR25945 - UCS: fixed default y dir calculation of 3point option - now it is cross product of z axis and x dir instead of the former simple shift in y axis from origin point.
SR25951 - GRIP EDIT: command names used for grip editing were corrected (i.e. 'GRIP STRETCH' was used instead of 'GRIP_STRETCH').
SR25957 - SHADEMODE: fixed error when displaying unresolved 'ByLayer' color (entity had 'ByLayer' color, and the layer as well).
SR26043, SR25882 - TXTEXP command: last straight segments after curved ones in TTF text contours were processed incorrectly, leading to chamfering of adjacent corners.
SR26134 - TABSURF, REVSURF: fixed processing of LwPolylines.
SR26221 - SNAP: intersection snap between two parallel polylines that were just slightly apart (<= 1e-6) was failing.
SR24751 - OPEN: Implemented opening of multiple documents by command line.

Fixed

The model/layout bar under the main view was missing in Ubuntu 10.10. When the bar was clicked, bricscad crashed. This issue was caused by a change in the gtk library. A callback function that used to be triggered when a new document window is opened, is no longer triggered. Among others, this callback function is required for initializing the model/layout bar. The issue has been fixed by explicitly calling the callback function on every action that opens or creates a new document.
