Measurement / interaction:
- Circle-center snap in Snap(): click near a circular edge to snap to its
center (hole-to-hole pitch measuring); nearest of vertex vs circle wins
- Esc cancels pending multi-step measurement, then exits mode, then gizmo;
hotkeys P/D/E/F/C/A/M toggle measure modes (ignored while typing)
- Volume/centroid via mesh signed volume (open-shell detection rejects
unreliable results); tree context menu adds it as a measurement
View / UI:
- Standard views (Iso/Front/Top/Right, Z-up) + orthographic toggle;
gizmo overlay camera now switches type to match main camera
- GridSplitters for tree/measurement panels; node tooltip shows AABB LxWxH
- Tree name filter (matches + ancestors + subtree, auto-expand);
context menu: isolate node / invert visibility / show all
- Settings persistence (window bounds, unit, 10-file MRU) in
%LOCALAPPDATA%/STPViewer/settings.json; recent-files dropdown
Files / section:
- Interference accepts >=2 visible files, checks all pairs
- Export STEP: visible Solids/Shells at current aligned positions via
CADability ExportStep; SmokeTest --export-test round-trip verifies
- Custom section plane by picking 3 points (axis combo 3-pt); plane
position generalized to AABB-corner projection; numeric position input
- Bump version to 0.5.0
