Gorgious	592c51b526	Add interactive gizmo system for editing parmeterized door Implement visual parameter manipulation in 3D viewport with reusable gizmo components. Features snap-to-mesh (Ctrl), precision mode (Shift), and real-time feedback. Includes cone gizmos for dimensions, arc gizmo for swing direction, and icon gizmos for edit controls. Gizmos are globally are individually toggleable in the addon preferences. May be expanded upon later to add gizmos to other paramaterized elements (window, railing, roof, stairs, array, ...). Unfortunately gizmos can't tap into the builtin snap system or bonsai snap system which is built for modal operators so gizmos implement yet another custom rather naive snap system.	2025-11-23 20:16:27 +01:00

Ryan Schultz	bfd5b1bede	add to https://github.com/IfcOpenShell/IfcOpenShell/commit/57bc709b6fef6381bbb2810da15e568290c4a77a : Fix elevation display by converting from project units to meters on import When importing spatial decomposition, get_storey_elevation() returns values in the project's unit system (e.g., feet), but format_distance() expects values in meters. Added unit_scale conversion (elevation * unit_scale) before formatting to ensure elevations display correctly regardless of project units.	2025-11-22 16:53:28 -06:00
Ryan Schultz	0d0b6cc6b2	Additional fixes to https://github.com/IfcOpenShell/IfcOpenShell/commit/57bc709b6fef6381bbb2810da15e568290c4a77a	2025-11-22 15:40:47 -06:00
Ryan Schultz	57bc709b6f	Fix imperial unit conversion for plan and section level decorators Level annotations were incorrectly converting feet to meters and back, causing values like 3ft to display as 9'10". Updated format_value() to accept in_unit_length parameter and pass it to format_distance(), since Blender's Z coordinates are already in project units. - Add in_unit_length parameter to BaseDecorator.format_value() - Set in_unit_length=True in PlanLevelDecorator.draw_labels() - Set in_unit_length=True in SectionLevelDecorator.draw_labels()	2025-11-22 14:39:13 -06:00
Ryan Schultz	b7b6e4aadf	Consolidate format_distance functions and fix imperial unit formatting Replaced duplicate format_distance in unit.py with comprehensive MeasureIt-ARCH version from helper.py. Fixed critical floating point errors by changing inPerFoot from 11.9999 to 12.0, eliminating spurious fractions on whole numbers. Implemented auto-precision detection to simplify fractions (64/256 → 1/4) while preserving precise values like 3/256 when needed. Enhanced imperial parsing to support flexible input formats (optional symbols, mixed fractions, leading decimals) and fixed suppress_zero_inches functionality in dimension annotations.	2025-11-22 13:49:30 -06:00

Gorgious	452d0f6023	fix - handle float64 checksums from files saved in previous Blender versions Files saved in previous Blender versions stored position checksums as float64 (24 bytes for location, 72 bytes for rotation), but the current code only expected float32 format. This caused a shape mismatch error (6,) vs (3,) when comparing checksums during save operations. Added byte size detection in is_moved() methods to automatically handle both old float64 and new float32 checksum formats, ensuring backward compatibility with files from previous versions. Fixes ValueError when saving IFC files loaded from older Blender versions.	2025-11-21 23:23:57 +01:00

Andrej730	9eedbc6f72	FindOpenCASCADE - fix linking issue with non-configs #7390 Unexpected consequence of #7365 - previously `OPENCASCADE_LIBRARIES` supposed to be a list of libraries filepaths, but after refactor `OpenCASCADE_LIBRARIES` end up being both list of library names and list of filepaths. And since link directories for the names was not provided, it failed to find the libraries to link. If using OpenCASCADEconfig it wouldn't fail as cmake would evaluate library names as imported target names. To fix it and simplify it even further, in case of manually provided paths, it now creates `OpenCASCADE_INTERFACE` target and stores it in `OpenCASCADE_LIBRARIES` - target will automatically have all the includes, library names and library dirs.	2025-11-21 18:28:06 +05:00

Andrej730	1b249b1013	build-deps - fix very very old bug with `GitCloneAndCheckoutRevision` not always checking out revision Since this if-block happens in parentheses, then all `%VAR%` are expanded at the start and then `%ERRORLEVEL%` and `%RET%` values have no relation to the actual result of `git clone`. So if user were (un)lucky, then `%RET%` would be not yet set to "0" (by the previous function call), then it would skip checking out revision. `GitCloneOrPullRepository` had similar issue, but it was never used anywhere.	2025-11-21 18:28:05 +05:00

Andrej730	158fe92644	HDF5Config.cmake - use CMAKE_SOURCE_DIR instead PROJECT_SOURCE_DIR It doesn't really matter in this case - it matters really only for FindLibXml2, because `PROJECT_SOURCE_DIR` point to svgfill, when it's config executed, instead of `CMAKE_SOURCE_DIR` - so `CMAKE_SOURCE_DIR ` is never removed from the path, leading to cyclic calls.
