IfcCenterLineProfileDef: implement profile mapping

The mapping for IfcCenterLineProfileDef was a stub returning nullptr, so any swept solid using this profile produced no geometry. The dispatch then fell through to the IfcArbitraryOpenProfileDef parent mapping, whose open zero-area loop fails the face cast in the sweep mappings anyway. The taxonomy offset_curve item sketched in the earlier commented-out attempt is not implemented by any kernel (AbstractKernel throws not_implemented_error, the OpenCASCADE loop converter throws for it), so the offset is instead computed at mapping time. The centerline is offset to both sides by Thickness/2 in the profile plane and closed with end caps, using straight miter joins at polyline vertices. This preserves the constant thickness along the curve that the profile definition prescribes, which the circular arc joins of a generic offset algorithm (the pre-0.8 BRepOffsetAPI_MakeOffset path) would violate, matching the design note from the earlier implementation. Centerlines with curved (arc or spline) segments are detected and rejected with a warning for now, keeping the previous no-geometry behavior for those. Verified with IFC4 and IFC2X3 test files, straight and L-shaped centerlines: output solids are watertight, mitered, and have exactly the expected thickness, extents and volume. This is the geometry-side prerequisite for the sheet-from-centerline authoring discussed in #2077. Generated with the assistance of an AI coding tool.

Petru Conduraru	2e3d4486ca	IfcCenterLineProfileDef: implement profile mapping The mapping for IfcCenterLineProfileDef was a stub returning nullptr, so any swept solid using this profile produced no geometry. The dispatch then fell through to the IfcArbitraryOpenProfileDef parent mapping, whose open zero-area loop fails the face cast in the sweep mappings anyway. The taxonomy offset_curve item sketched in the earlier commented-out attempt is not implemented by any kernel (AbstractKernel throws not_implemented_error, the OpenCASCADE loop converter throws for it), so the offset is instead computed at mapping time. The centerline is offset to both sides by Thickness/2 in the profile plane and closed with end caps, using straight miter joins at polyline vertices. This preserves the constant thickness along the curve that the profile definition prescribes, which the circular arc joins of a generic offset algorithm (the pre-0.8 BRepOffsetAPI_MakeOffset path) would violate, matching the design note from the earlier implementation. Centerlines with curved (arc or spline) segments are detected and rejected with a warning for now, keeping the previous no-geometry behavior for those. Verified with IFC4 and IFC2X3 test files, straight and L-shaped centerlines: output solids are watertight, mitered, and have exactly the expected thickness, extents and volume. This is the geometry-side prerequisite for the sheet-from-centerline authoring discussed in #2077. Generated with the assistance of an AI coding tool.	2026-07-25 08:34:14 +03:00
Petru Conduraru	89523999b3	Bonsai: fix UnboundLocalError crash in polyline angle calculation angle_round_threshold was only assigned inside the `distance > 0` branch of calculate_distance_and_angle, but read unconditionally whenever should_round is True. When the mouse sample coincides with the last placed point (distance == 0), such as the first mouse move after placing a wall's start point on a YZ plane view, this crashed the modal wall tool. angle_round_threshold is a fixed cutoff unrelated to whether distance is currently zero, so it is now assigned once before the branch.

Petru Conduraru	51ab38de27	Fix ci-bonsai-daily: configure unmerged_blobs mock in git_mergetool tests (#8574 ) test_returns_none_when_report_file_absent/empty build a MagicMock repo without configuring index.unmerged_blobs(), so it returned a truthy MagicMock and git_mergetool's load-bearing "unresolved conflicts remain" fallback (tool/ifcgit.py:646-647) returned that list instead of None - failing "assert [] is None". The production fallback is correct and intentionally left untouched; the tests just misrepresented the "mergetool resolved cleanly" scenario they are named for. Set mock_repo.index.unmerged_blobs.return_value = {} in both. Verified in headless Blender: test/tool/test_ifcgit.py::TestGitMergetool 2 failed / 1 passed -> 3 passed.

Petru Conduraru	e759135608	Bonsai: cache-bust webui static assets so shipped JS/CSS changes reach users Browsers were caching /static/js and /static/css for the standalone webui (costing, gantt, drawings, index, demo pages) indefinitely, so a shipped JS fix (e.g. the Download CSV button) would only reach a user after a manual hard refresh. Two changes, applied consistently across all five webui pages. 1. Every locally served link/script tag in the pystache templates now carries a ?v=<bonsai version> query string, falling back to a static asset mtime hash when BONSAI_VERSION isn't set (e.g. running sioserver.py standalone). Since get_bonsai_version() includes the build's commit hash, the token changes on every shipped update. 2. Responses under /static/ and /jsgantt/ now carry Cache-Control: no-cache, must-revalidate. This covers what query stamping alone can't reach: cost.js and gantt.js statically import utilities/costui.js by a fixed relative path with no query string, so that nested module still needed server side revalidation to pick up changes. Verified against a live aiohttp instance of sioserver.py: rendered HTML for all five routes shows the stamped URLs, and the token changes when BONSAI_VERSION changes between two server runs. A conditional GET against a static file with a stale If-Modified-Since header confirms the cheap 304 revalidation path still works. Also used this instance plus a real headless Chromium (Playwright) to click test the previously untested Download CSV button on the costing page. The ribbon renders it correctly, and clicking it (with a synthetic cost-items table injected into the DOM to stand in for a connected Blender's data) triggers a real Blob download with the correct filename and CSV content. No bug found, the button works as intended. AI-generated with Claude Code.	2026-07-24 11:32:34 +02:00
Petru Conduraru	1df738d968	ifc5d: match cost schedule export columns to the Bonsai cost panel (#6251 ) Stefano's final ask on #6251 was specific: the ODS/XLSX export should show exactly what the cost panel shows, ID (Identification), Name, Quantity, Value, Total Cost, no more, no less. The previous fix in this PR removed the internal bookkeeping columns but still exported Description, Unit and a per-category cost breakdown (Labor Cost, Material Cost, etc), none of which appear in the panel. Presentation formats (.ods/.xlsx) now use an explicit allow-list of columns instead of a block-list of internal ones, and relabel headers to match the panel's own wording (ID / Value / Total Cost). The .csv format is unchanged: csv2ifc still reads back the extra bookkeeping columns for the import round trip, which is why it keeps them. Also add a "Download CSV" button to the browser costing view (Generate spreadsheet browser), which previously only offered a clipboard-based Copy Selected. It reuses the already-rendered table (respecting the user's column visibility settings) and triggers a real file download, dropping only the UI-only Actions column.

Petru Conduraru	98c28a1f30	ifc5d: professional grade ODS/XLSX cost schedule export #6251 Three defects reported against the Costing tab export: 1. XLSX export crashed with ModuleNotFoundError: xlsxwriter was never bundled with Bonsai. Port the writer to openpyxl, which ifccsv already uses and Bonsai already ships, so it works out of the box. 2. Every ODS cell was written as a string (numbers as text), and the formula branch was dead code: it compared against 'Total Price' / 'Rate Subtotal' while the headers are 'TotalPrice' / 'RateSubtotal'. Numeric columns are now typed float cells and TotalPrice becomes a real formula: Quantity*RateSubtotal on leaf items, SUM over the direct children's TotalPrice cells on sum items. 3. Internal bookkeeping columns (Id, ItemIsASum, Hierarchy, Index, Quantities) leaked into the presentation formats. ODS/XLSX now hide them; CSV keeps them since csv2ifc consumes them for the round trip. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-24 11:32:34 +02:00
Petru Conduraru	21122c0d28	Resolve nested complex quantity paths in the selector (#2041 ) get_element_value could not reach the members of an IfcPhysicalComplexQuantity (or IfcComplexProperty) by their natural path. util.element expands a complex quantity into a dict whose nested members live under a "properties" sub-dict, but the selector's dict navigation only looked at the top level, so "Qto_Custom.Layer1.Width" returned None and IfcCsv exported nothing for it. Only the internal "Qto_Custom.Layer1.properties.Width" path worked. When a key is not a direct member of the value dict, descend into its "properties" sub-dict so nested quantities/properties resolve with the natural "Set.Complex.Nested" path. Direct keys still take priority, so the explicit ".properties." path stays backward compatible and the regex branch is untouched. Verified: Qto_Custom.Layer1.Width -> 0.1 and Layer1.Height -> 2.5 (were None), the sibling simple NetArea still resolves, the legacy .properties. path still works, and IfcCsv now exports the nested value. test_selector.py: 38 passed (adds test_selecting_a_nested_complex_quantity).
