Curved leads turned with the contour winding, which is backwards on outside perimeters: arc lead-ins arrived against the cut, and Line + Arc / arc lead-outs went the long way round on one winding. LeadTurn now gives the arc's turn direction for emission, the pierce-zone check and the preview, and the arc geometry mirrors with it. At convex outside corners, curved lead-ins use the first-cut edge's normal and arc lead-outs the last-cut edge's, whichever edge was picked. ArcLeadIn gains SweepAngle (degrees, (0, 180], default 180) in the cutting panel, settings, nest files and cut pins; older files read as 180. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
