geom

Booleans about twice as fast: point-in-mesh tests through a per-direction grid (sampling checks), one mesh of the result for both its volume and membership checks, operand volumes from their meshes, and the intersection tried at the coarser tolerance first (oracle run 10 → 5 minutes); free-form faces merge in the topology counts when their normals agree within 2.5°

render

Selection feedback and origin: hover and selected highlights (theme tokens), origin planes/axes/point at a fixed screen size with browser eye toggles, click-to-pick sketch planes and faces with camera animation (Finish Sketch returns), multi-select dialog inputs with pre-selection, tangent chains and face-to-edges, window/crossing box selection, shell/draft/mirror/hole dialogs

sketch

Exact profiles for splines of any degree (a degree-4…7 Bézier segment kind, Seg2::Bezier, extruded as B-spline edges) and for free-form curves cut by crossings (exact sub-curves whose ends are moved to the true crossing, found by Newton; polylines only where that fails)
