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). Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
