Hakan Seven	27aca41dd1	feat: plinegen + SAB parsing for Solid3D/Region/Body ... LwPolyline PLINEGEN=0 (DXF default): emit SegmentedLines with NaN separators between vertex-to-vertex segments; wire_gpu resets arc-length to 0 after each NaN so linetype pattern restarts per vertex. PLINEGEN=1: existing Contour path unchanged (continuous pattern). WireModel gains plinegen field propagated through tessellate pipeline. Solid3D/Region/Body: call SabReader::read() when parse_sat() returns None due to binary SAB format (DWG files / newer AutoCAD exports).

Hakan Seven	5cf7a19ca8	feat: Region and Body entity tessellation + render ... Refactors solid3d_tess to share tessellate_sat() across Solid3D, Region (2D planar ACIS body), and Body (3D ACIS body). populate_meshes_from_document() and add_entity() now tessellate all three entity types into GPU MeshModels when ACIS SAT data is available.

Hakan Seven	a99115bda5	feat: Solid3D (3DSOLID) ACIS tessellation ... Parse SAT geometry directly into GPU MeshModel without going through the truck B-rep pipeline: • plane-surface faces → fan-triangulate the coedge-loop polygon • cone-surface faces → parametric grid (handles cylinders and cones) • sphere-surface faces → UV sphere grid (GRID_U × GRID_V) • torus-surface faces → UV torus grid Scene integration: • add_entity(): tessellates Solid3D on insert, stores in scene.meshes • erase_entities(): removes mesh from scene.meshes on delete • populate_meshes_from_document(): rebuilds all meshes on file load and undo/redo (called alongside populate_hatches/images) ROADMAP updated: Solid3D tessellation marked ✅ in sections 2.12, 14.
