Improvements
ASSEMBLY MODELING:
MECHANICAL BROWSER: in 'Group by entity' mode, constraints now are attached to corresponding component insert nodes.
BMREMOVE: command was removed - now the regular erase command or the Del key can be used instead.
BMUNMECH: confirmation prompt has been added.
QUAD:
Quad was suppressed for tables and MInsert blocks.
Select command was added for regular blocks.
PREVIEWNESTEDENTS: system variable has been removed - instead the PREVIEWSUBENTS range has been extended.
SR36817 - AUTOCOMPLETE: single-click instead of double-click to close the panel and start the selected command.

Fixes
ASSEMBLY MODELING:
Cut and paste did not work for standard components in some cases.
BMFORM: duplicate component names were generated in some cases.
BMINSERT: rotation angle, base point and insert name were not remembered in Multiple mode.
EXTENTS: the extents of a viewport, placed on a layer that is frozen in the overall paper space viewport, were not taken into account during ZOOM/EXTENTS nor during PRINT/EXTENTS.
TIPOFDAY: using an empty tipofday file caused an application crash.
SR22148, SR24516, SR30690, SR31442, SR33750 - ASSOCIATIVE DIMENSIONS: fixed problems when moving associative dimensions.
SR29380, SR33155 - 'FROM' snap option: dynamics were drawn from the original point instead of from the selected point.
SR35235 - AEC: a crash occurred upon opening a user-provided drawing containing AEC entities.
SR35535 - PRINT: offset was handled incorrectly in Layout plot area print mode (offset value used had wrong sign and was not scaled).
SR36847 - XREF: disappeared in layer preview and model space after changing a layer used by the xref - regen was required to make the xref visible again.
SR36996 - MLSTYLE: BYLAYER and BYBLOCK options were missing from the color picker.
SR37005 - OLE: in display modes other than 2dwireframe, OLE entities were not displayed, printed or exported.
SR37022, SR37029 - LOCALIZATION: several corrections/improvements for text strings used in dialogs and command prompts.
SR37033 - MLSTYLE: crash occurred after changing a multiline linetype and closing the Drawing Explorer.
SR37047 - DIMCENTER: center mark and center lines should use CELTYPE value instead of BYBLOCK for linetype and CECOLOR instead of DIMCLRE for color.
SR37058 - SHEET SETS:
Sheet sets coming from another location (or older application version) can contain paths that do not exist on the current system. These paths are now resolved as much as possible upon opening of the sheetset.
New Sheet Set dialog:
reorganized pages
display nested subsets
display subsets also when creating sheetset from existing drawings
added context menu to layout list for selecting none/all/first of drawing
Field dialog: sheetset fields value was not displayed unless one of the format types was selected.
Added 'total number of sheets' to sheetset properties and sheetset fields: SheetSet.SheetCount and Subset.SheetCount (BricsCAD-only field types).
SR37078 - LOCALIZATION: allowed 'Offset' to be translated in two different ways for the Russian translation.
SR37090 - IMAGEHLT: the system variable to control whether only the image frame or both frame and image should be hilited was not obeyed.
SR37101 - LOCALIZATION: missing linefeed in MVSETUP command prompt caused misbehavior.
SR37139 - MVIEW: newly created viewports should be unlocked by default.
SR37140 - MLEADER: a crash occurred when transforming an mleader that has no block content.
SR37149 - AUTOCOMPLETE: should be disabled while entering a new layout name.
SR37170 - MLINE: changing the scale value of an mline using the Properties Bar had no effect.
SR37191 - LOCALIZATION: the command name was not shown in the autocomplete panel if the global command name was the same as the localized name.
SR37215 - MLSTYLE: corrected Multiline Style dialog caption.
SR37217 - MLSTYLE: creation of style names containing spaces was allowed - it shouldn't be.
SR37235 - LOCALIZATION: "Open" string could not be translated in Russian version.

Applications
LISP - SSGET: improved performance when (ssget) is called very often (i.e. in loops), by reducing the number of GarbageCollections.
LISP - TBLSEARCH: significantly improved performance for (tblsearch) and (tblnext), factor >= 2.
.NET: Fixed managed palette regression introduced in V13.1.5
SR34953 - .NET: Geometric Extents Minpoint was not properly calculated for 3dpoints.
SR35755 - .NET: Document TransactionManager should not properly flush graphics on commit.
SR36829 - LISP/SDS/BRX: the command line output for the INSERT command was always displayed, regardless the CMDECHO value.
SR35894 - .NET GripOverrule: an exception occurred when adding new GripData objects to a GripDataCollection.
SR36985 - COM: "Rotate" method - input point (rotation center) was handled as WCS point instead of UCS point, and UCS plane/Z-Axis must be used for rotation.
