Improvements to BricsCAD Core
COLORBOOKSWe now show information about colorbook colors found in drawings
created in by other applications.
COPYGUIDED and MOVEGUIDEDMultilines are now supported as reference curves for the
COPYGUIDED and MOVEGUIDED commands.
The calculation of the center of the detail is improved for more complex scenarios.
The CopyGuided and MoveGuided tools were added to the "Modify" menu and toolbar. SR100484

OPTIMIZEImproved gap-closing logic.
OverkillThe Ribbon icon was renamed to be consistent with the command name.
Parameters and Constraints PanelFixed a crash that occurred when a specific set of
clicks were made in the P&C Panel. This was a regression.
Point CloudsAdded icons for POINTCLOUDREFERENCE and POINTCLOUDDELETEITEM in ribbon
and toolbar, and added point cloud icons in the quad.
An issue in pre-processing point clouds is fixed; the application now delivers pertinent feedback to the user. SR119329
POINTCLOUDCROPSOLIDThe new POINTCLOUDCROPSOLID command enables you to convert an

between generated section blocks in model space. BIMSECTIONUPDATE identifies any overlap between
generated section blocks in model space, and offers to run the BIMALIGNSECTIONBLOCKS command.
A new result block is created when an old result block is being used by another viewport. This allows users to place two viewports on the same sheet, viewing the same BIMSECTION result block,
while using different parameters (elevationfill, customization, et al).

.NETImplemented the BoundaryRepresentation.Shell.ShellType
.NETIn V21 we introduced automatic theming for PaletteSet controls. This introduced
some difficulties for porting WinForms based palettes because many standard controls do not work
well with the default dark color theme. We have now reverted back to the previous behavior, leaving
form colors unchanged. Any third party WinForm controls wishing to continue using automatic theming
can do so by explicitly disabling the SupportsTransparentBackColor control style in the palette
.NETOverriding the themed background in a user Palette is more reliable now. This
is useful when legacy controls are not easily themed, and it is necessary to insert a solid white
background panel. SR118365

BIMSECTIONUPDATEAxis labels are no longer displayed in section result drawings
when the "Display Labels" option is turned off for a BIMGRID.
Drawing CustomizationsAdded a "nested property search" option to the filters. This
allows users to control which property is used for filtering in assemblies: the default for the
assembly, or the default for the nested entities. This makes it possible to customize entities
inside assemblies, separately.
Added a versioning system for drawing customizations.
Exposed additional properties for use in drawing customizations.
Project BrowserAdded a new dialog for creating a project library, and the option
to connect all drawings to the new library.

Improvements to Civil
LANDXMLEXPORTImperial 'miles' units are now supported. If units are not specified,
the user is asked to specify the desired units.
LANDXMLIMPORTUnits are now considered on LandXML import. When unsupported units
are set as drawing units, the user has three options: 1.) the geometry is scaled, 2.) the geometry
is imported without units, or 3.) the command is canceled.
UCS for Vertical Alignment ViewsIt is now possible to set the UCS origin at the
bottom-left corner of a Vertical Alignment View, when the UCS is defined by entity. SR117284
3D CONSTRAINTSThe default values applied to 3D dimensional constraints upon
creation are now computed from geometry, with maximal precision. They are no longer affected
by (or limited by) the LUPREC and AUPREC precision settings. SR116819
3D MouseA period of sluggish cursor movement after startup was caused by
3D Mouse resource initialization. This initialization was performed even when there was no
3D Mouse installed. We've improved the startup experience by running the initialization
sequence only when a 3D Mouse is installed. SR116914
3D Display and RenderingA bug in an AMD display driver caused the tiles created by
the RENDER command to be scrambled. Another consequence of the bug caused 3D screen output
to run one frame behind real-time. This caused some user actions to not be immediately visible
(e.g. highlighting, de-selection, etc). Both of these issues are now fixed. SR105040SR113825SR115072SR115531SR116955SR117221
BricsCAD: Application WindowIt is now possible to start BricsCAD with the
(main window) minimized. Floating tools will no longer be shown while BricsCAD's main window is
minimized or hidden. This is a regression since BricsCAD V18.2.20; potentially even earlier.
BIMSECTIONUPDATEComposition/Material names with special characters no longer cause
BricsCAD BIM to crash. SR103983
BIMSECTIONUPDATEFixed volume section result generation when a polyline entity is

Drawing ExplorerThe grid view of the Block Explorer panel could take a long
time to display on first open, when the drawing was stored on a slow disk (or being accessed
across a slow network connection).
We've improved performance in these situations. SR82203SR82828
The global material now uses "Inherit" as diffuse color instead of "white".
Drawing ViewsImproved the reaction time of the ISOLATE/UNISOLATE commands. SR116497
EXPORTPDFFixed some potential issues in the EXPORTPDF command.

Library PanelItems shown in the Library Panel can now be translated properly
in localized versions of BricsCAD. SR116508
Library PanelForcing Thumbnail generation sometimes activated a random application
window. It drove us a bit buggy, so we fixed it. #haha
Linetype GenerationThe incorrect linetype scale is no longer applied
when generating linetypes in particular cases (e.g., an XCLIPped Insert, when a global
LTSCALE is set). SR116661SR116959SR116974
Localized Versions of BricsCADWe fixed several translation issues. SR116088 SR116948
MECHANICAL WorkspaceWe circumvented a crash that could occur for some users,
when opening the Mechanical workspace. SR115489SR117421SR117459
NEW and OPEN dialogsThe last chosen drawing or template is now always displayed,
highlighted and with cursor focus, in NEW/OPEN dialogs.
OLE ObjectsPlotting of OLEFRAME entities with a rotated plot orientation was broken
in earlier versions of BricsCAD V21. This issue has been corrected. SR116674SR117861SR117909SR118052

stored in the RCP file.
Point Cloud ImportFixed an issue that caused the import of specific E57 files
to fail. SR 117096
RibbonUnder certain conditions the right-most ribbon tab did not move as the main
frame window was re-sized. This has been fixed. SR115934
SETBYLAYERSETBYLAYER applies "ByLayer" properties to linetypes, lineweights,
plotstyles, material and transparency settings.
Pressing 'Enter' to select the new license level now works correctly in license levels higher than
SettingsSome Layer name Settings can accept a Layer name that has not
yet been created, i.e. a 'future' layer. These 'future' layer names could not be displayed
or entered in the Settings dialog. This issue has been corrected.
A sub-set of the BricsCAD system Settings can have spaces in their names. These Settings could not
entered at the BricsCAD command line, because the required space bar press was interpreted as
an 'Enter' by BricsCAD. This issue is fixed, too.
.NETA custom Windows.Panel now updates as expected when its Icon or Title
properties are changed. SR116038
.NETA re-startable Windows.Panel, hidden by a 'Visible=false' flag before the

around a specified point.
SDS/BRXImproved compatibility for ads_entnext(), setting the "errno" environment
variable for a set of particular error cases. SR116763

APIs. These will break existing code that was written for BRX only: 1.) The BRX acedGrVecs(),
Lisp (grvecs), and .NET Editor.DrawVectors() functions now interpret input vectors in DCS
coordinates instead of UCS. 2.) The transformation matrix in acedDragGen() callback is now a WCS
transformation instead of UCS. SR68142SR71833
BRX/.NET/LispThe various APIs for getting the implied selection set, like (ssget
"I") in Lisp or Editor.SelectImplied() in .NET, now work as expected when the PICKFIRST system
variable is set to zero. SR113329

occurred when Modelspace tiled Viewport(s) are added, and a display operation is triggered
immediately afterwards (zoom, ddvpoint etc.). SR94110
