  SR114412 SR117275 SR117768
• TINSERTThe TINSERT dialog's block list is now sorted alphabetically.
  SR117117
• VIEWPORTPanning inside of a viewport now works as expected on Linux versions of BricsCAD.
  SR116837

Improvements to BIM

• BIMSECTION SCALEThe scale list of a drawing is used for the Bimsection scale property. This list can be edited via the "Scalelist edit.." item selection.
  SR101026 SR115350 SR115358
• 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.
  A progress bar is now displayed in the project setup dialog when BricsCAD BIM is analyzing the library's status and connecting drawings.
• QuickbuildingImproved Quickbuilding's ability to create a building from spherical or wedge-shaped solids.
  Improved the unit detection algorithm when detecting a building's story height.
  
  SR117236
• RVT ImportAdded auto-classification of imported entities as properly named BIM entities, whenever possible.
  SR115712 SR116654

Improvements to Communicator

• STEP File IMPORTAdded layers conversion on STEP file import, when Communicator is running in background mode.

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

Fixes

• 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.
  SR105040 SR113825 SR115072 SR115531 SR116955 SR117221
• BricsCAD: Application WindowIt is now possible to start BricsCAD with the application (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. #oops
  SR113703 SR117067 SR117559
• BIMSECTIONUPDATEComposition/Material names with special characters no longer cause BricsCAD BIM to crash.
  SR103983
• BIMSECTIONUPDATEFixed volume section result generation when a polyline entity is present in a BimGrid. The problem is fixed, and we've temporarily removed support for Polyline entities in BIMGrids. More to come, soonest.
  SR115630
• BIMIFYNow performs better than ever! #SoundsLikeMarketing, but really, it does.
• COMMANDLINEScroll bars are no longer (improperly) trimmed in the (old style) floating panel.
  SR115918

  SR114842 SR116248 SR116268 SR116574 SR116930 SR117388 SR117476 SR117642 SR117856 SR118047 SR118022
• 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.
  SR82203 SR82828
• Drawing Template The global material now uses "Inherit" as diffuse color instead of "white".
  SR116984 SR117293
• Drawing ViewsImproved the reaction time of the ISOLATE/UNISOLATE commands.
  SR116497
• EXPORTPDFFixed some potential issues in the EXPORTPDF command.

  SR117302 SR117327 SR117504 SR118081
• 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).
  SR116661 SR116959 SR116974
• 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.
  SR115489 SR117421 SR117459
• 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.
  SR116674 SR117861 SR117909 SR118052

• SETBYLAYERSETBYLAYER applies "ByLayer" properties to linetypes, lineweights, plotstyles, material and transparency settings.
• SETLICENSELEVEL Pressing 'Enter' to select the new license level now works correctly in license levels higher than 'BricsCAD Pro'.
  
• 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 be entered at the BricsCAD command line, because the required space bar press was interpreted as an 'Enter' by BricsCAD. This issue is fixed, too.
