CypherNaugh_0x 9508ee749c Shell refuses a wall thicker than a rim instead of returning a corrupt body: the topology-preserving face offset now checks every planar face's moved loops, and a loop that turns inside out or two loops that cross (a rim or ledge narrower than the move, e.g. a bowl opening sliding past the slab's outer edge) is an error naming the spot. Before, the self-crossing cavity went into the boolean and the shelled body came back with roughly twice its volume and its centre of mass outside the body, so every later cut failed its volume check ...

The check is geometric, not a tuned threshold: on the reported basin (18 mm rim, sloped bowl wall) the rim strip reaches zero width at 15.17 mm and the shell is refused from there on. Tolerances only absorb rounding (scaled to the body size), and at most 2000 straight edges per face are compared pairwise. Arc edges and curved faces are not checked.

This is a guard, not the full fix. Building such a shell needs the offset to change topology: drop the strip that collapses and let its neighbours meet, as offset_body already does for rounds thinner than the move, extended to planar faces. That is substantially more work in the most delicate part of the kernel (rims, ledges, steps, arc-bounded strips) and is left for a separate change; until then the workaround is to model the hollow directly (an offset loft and a box cut).

Section Analysis takes a world coordinate: inspect.section {plane, at} places the cut at that coordinate on the named plane's axis (XY: Z, XZ: Y, YZ: X), so XZ's -Y normal no longer flips the sign; the params doc gives each named plane's normal; the result reports axis and at for named planes. at with offset, or with an {origin, normal} plane, is an error

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°

Silhouette edges on curved surfaces: drawn in the surface shader where it turns away from the eye (about 1.5 px, only on the visible surface, so nothing shows through thin walls), in the viewport and live previews; snapshots draw them too. The back-face outline pass is gone

ui-egui

Drawing connects to existing points: a new point landing exactly on an existing point (the origin too) gets a coincident constraint in the engine, for every drawing command and every caller (MCP, scripts, clicks), in the same undo step; connect: false opts out. Re-tying an existing coincident returns it ("existing": true) instead of failing; the UI's after-the-fact tie_snaps is gone
