Hakan Seven	d7422b9396	fix: store arc angles in radians	2026-05-03 20:14:28 +03:00
Hakan Seven	c51eeb4ad0	feat: extrude Arc and Circle thickness along WCS normal ... Arc: tessellates bottom + top arcs (32 segs each) with 2 endpoint walls. Circle: tessellates bottom + top circles (64 segs each) with 4 quadrant walls. Both use TruckObject::Lines with NaN-separated segments.

Hakan Seven	674a94f756	feat: implement OCS→WCS transform for Arc, Circle, and Line ... Entities carrying a non-standard extrusion normal (normal ≠ (0,0,1)) were rendered flat in the XY plane. The DXF arbitrary-axis algorithm is now implemented in scene::transform::{ocs_axes, ocs_point_to_wcs} and applied during tessellation of Arc, Circle, and Line so they render correctly on tilted planes in 3D DXF files.

Hakan Seven	e2f5715de8	fix: correct arc sweep direction for reversed normals and mirrored blocks ... - Arc rendering now respects the normal vector: when normal.z < 0 the midpoint is placed on the clockwise side so the curve sweeps the right way - Removed spurious .to_radians() / .to_degrees() round-trips in arc.rs (angles are already stored in the unit the trig functions expect) - apply_grip and apply_transform use consistent angle units - normalize_insert_entity no longer converts arc angles; the old conversion was only needed by the now-removed .to_radians() call in to_truck - Added fix_mirrored_arc: swaps arc start/end angles when the INSERT has a mirrored scale (x_scale * y_scale < 0) so exploded arcs curve correctly Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-22 21:48:21 +03:00
