What's new:

• UK 2020 Bar Conversion Command (AB_CONVERTUK2020): New command to convert all rebar entities in a drawing from BS 8666:2005 to BS 8666:2020. Prompts for a source DWG file, creates a copy with a _UK2020 suffix, and reports conversion results.
• Bar Mark Start Field: Added a "Bar Mark Start" input field to the Area Zone dialog with save and load persistence, giving users control over bar mark numbering.
• Force Straight Bars Option: Added a "Use straight bars only" checkbox to the Area Zone dialog. The setting persists to Area.xml and replaces previous hardcoded behavior.
• Z Leader Command: Added a Z Leader command to assist with annotating 3D rebar models.
• Document Reactor Re-enabled: Re-enabled automatic bar style reloading when switching between open documents. Includes proper cleanup on unload and null safety guards.
• Schedule Toggle Label Preservation: The schedule toggle command (ab_range) now preserves custom labels containing "none" instead of overwriting them with the default template.

Bug fixes:

• Stepped Range Orange Border: Fixed all bars in a stepped range showing the orange selection border simultaneously. Stepped ranges produce many schedule rows from a single CAD entity, so every row shared the same CAD ObjectId. All rows matched the stored selection ID and all received the orange border. Now uses a Mark|Member key that uniquely identifies each individual display row regardless of the underlying entity ID.
• GlobalSettings Save Behavior: Replaced per-keystroke saving with LostFocus-based saving to prevent excessive XML writes and unnecessary CAD regens. Also wired up missing save handlers for several checkboxes (InsertHeading, MergeMember, OnlySumWeights, Schedule0, WLOneTable, LogVerbose) and fixed a ComboBox race condition during repopulation.
• COM Bar Creation (DetCode): Bars created via COM were visible in CAD but could not be read back via SelectAll(). Fixed by initializing the DetCode property during bar creation in DrawBar() and DrawBarGlobal().
• Area Zone Bar Grouping Rewrite: Replaced GroupBarsSort/MakeGroups with a new SplitIntoLanesAndProcess approach using RegionIndex for correct lane separation and consistent step detection with 20% tolerance.
• Straight Bar Detection Fix: Fixed straight bar detection in Area Zone for UK and international rebar codes.
• 3D PlotAll Rendering for Range Bars: Fixed VSIDE/VTOP/VBOT range bars not rendering correctly along the range line when PlotAll was enabled. The rangeSolid was being saved after the pln2wrld transform instead of before it.
• rangeSolid Cache Invalidation: Fixed stale cached range bar geometry persisting after changes to cover values, bar diameter, bar style, flip mode, bar angle, and bar dimensions (A, B, C, etc.).
• BLDOUBLE Color Rendering: Fixed 12 locations where BLDOUBLE offset lines and centerlines used a raw color index instead of the display color that respects style and highlight settings.
• Template Load Crash (ACCESS_VIOLATION): Fixed a crash when opening templates containing rebar objects at CAD startup. Caused by partially initialized AcString members in abakBarStyle objects. Fixed with SEH protection and null checks in ShapeReader.
• Preview Cache Crash: Fixed a crash caused by sl_live being used before initialization in OnInitDialog. Added null checks and fallback defaults throughout the preview cache.
• PlotAll Hiding Bars with No Range Line: Fixed bars without a range line becoming invisible when PlotAll was ON. Now only hides the insertion bar when PlotAll is ON and a range line actually exists.
• Leader Text Rotation in Print Preview: Fixed incorrect text rotation when plotting from paper space with a rotated viewport UCS. Now detects plot context via AcGiContext::isPlotGeneration() and uses stored WCS rotation directly.
• Selection Jumping During Delete/Modify: Fixed the selected bar losing highlight after a grid refresh. Now stores the selected bar ID before refresh and restores it after, with re-entrancy guards.
• Sentry Error Fixes: Fixed a bug in LoadValidDiameters() where all type ranges shared the same diameter list reference. Added null safety and exception handling in SelectAll(), BarsToDisplay(), CreateRegion(), and SubtractRegion().
• ExplodedBarManager Crash: Fixed an index-out-of-range crash in SafeParseDimensions() when accessing the third element of a dimensions array.
• ShapeReader Cache State Issues: Removed early-return cache optimizations in SetCurrentCode() and SetCurrentRod() that caused stale state, inconsistent ShapeReader behavior, and step range leader grip bugs.
• Country Code Mismatch Fallback: ShapeReader now falls back to a prefix match when an exact code list match fails (for example, a bar using "BS 8666:2005" when the config differs). A warning is shown once per session.
• CUI Menu Reload Fix: Fixed CUI menu loading by adding a proper reload function.
• COM Memory Corruption and Leaks: Fixed memory corruption and memory leaks in the COM interface, and optimized palette operations to reduce lag.
• VDOT Text Position: Fixed dot-view leader text being positioned at the attachment point instead of the text endpoint.
• BricsCAD Style Loading: Fixed bar styles not loading on BricsCAD during rendering. The ensureDatabaseStylesLoaded() call was guarded by a _DBXAPP preprocessor define that excluded BricsCAD builds.
• Rendering State Mutation (sRngl): Fixed worldDraw permanently modifying the range line mode. Empty or coincident range points forced sRngl = 1 which persisted beyond the render call, corrupting entity state without write access. Now saves and restores the original value.
• Old Drawing Style Loading (ABAK_BSTYLE_CUR): Fixed old drawings failing to render when the active bar style exists only in ABAK_BSTYLE_CUR and not in the ABAK_BSTYLE dictionary. The migration path requires write access which fails during worldDraw/REGEN. Now pre-loads the style during the read-only style loading pass.
• Document Reactor Double-Close: Fixed a double-close bug in the document reactor where the named objects dictionary was closed both inside readAllDatabaseStyles() and by the caller. Switched to the self-contained no-arg version which manages its own object lifetime.

Performance improvements:

• DataGrid Row Virtualization (Schedule): Fixed two UpdateLayout() calls that silently defeated IsVirtualizingWhenGrouping. The first was in UpdateGridData — called after setting ItemsSource, it forced WPF to materialize all row containers synchronously on every Update button click and on every bar add/modify/delete event. The second was in SizeChanged — when new data caused the vertical scrollbar to appear, the width change triggered an unconditional UpdateLayout() that materialized all rows again. With both removed, only the ~15–20 visible rows are ever created regardless of schedule size.
• Faster Member Selection: Selecting a member in the schedule now updates the grid instantly. Rapidly clicking through multiple members no longer causes excessive refreshes.
• Reduced Redundant Renders: Removed 3 redundant render calls after ItemsSource is set, and combined table scan operations into a single SelectAll() pass with one transaction (GetTableInfoAndRemove).
• Render Cache and LOD Gating (AddoBAR-Object): Added level-of-detail gating and improved cache management for 3D rendering operations.
• Bar Preview Render Caching (AddoBAR-Object): Added caching for bar preview rendering in dialogs to reduce repeated render work.

What's new:

• Configurable Shape Column Width: Added a new "Shape column width (mm)" setting in Global Settings that appears when "Draw bars on schedule" is enabled, allowing precise control over the bar/shape drawing column width (default: 15mm).
• Improved Table Layout: Shape column now always appears as the last column (after Custom column if enabled), ensuring consistent table structure and proper width calculations.
• Enhanced Backward Compatibility: Existing configurations automatically upgrade from 20 to 21 column width values, preserving user settings while adding support for the new Shape column.

What's new:

• Improved Configuration Persistence: Resolved an issue where global settings (Country/Code) would reset to defaults after a restart.
• Fixed Block File Pathing: Corrected a bug where abbreviated UI paths were being saved instead of full system paths, ensuring blocks load reliably.
• Configurable Table Rotation: Added a new "Rotate merged column text 90 deg" option under Table Settings, allowing users to toggle between vertical and horizontal text.
• Enhanced Auto-Save: All Global Settings now automatically save to Config.xml upon modification for a more seamless user experience.

What's new:

• Added Sentry-based error monitoring.

What's new:

• Updated MatchBar to match Shapecode as well.
