doc

Joints mate by default (Fusion's convention): origin B's z is turned against origin A's, so two picked faces meet face to face and B sits on A instead of inside it; Flip now means don't mate. File format 4 inverts older joints' flip so they keep their placement; as-built joints and rigid groups stay where they are

engine

document.units: unit-less user parameters that would change meaning keep the old unit written out (values are compared before and after); test with a length and a count

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°

kernel

Fillets of edges meeting at corners in any selection order: blends go one at a time in an order that works (a run along a planar loop waits for a selected edge meeting its inner corner, then bridges the arc it left), so three edges at a box corner give a sphere octant

mcp

3MF: export, and 3MF/STL import as mesh bodies

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)
