Overview

Projection of triangle meshes onto a plane and intersection with prisms: the bridge between the kernel's 3D meshes and its planar booleans. project_mesh folds a mesh onto a plane, unions the result and keeps holes, and reports how many edge-on triangles it dropped instead of hiding them. It computes geometry, not a footprint: choosing the mesh, the reference plane and what to include is left to the consumer (ADR 0066).

Changes

Latest release, 0.4.0 (2026-11-13):

Changed

• Breaking: requires axiolid-overlay 0.4, whose OverlayError is #[non_exhaustive] with the new HolesOverlap and PolygonsOverlap, and whose Region::new refuses rings that cross into each other. ProjectionError::Planar carries that OverlayError, so a match on it needs a wildcard arm (#448, ADR 0104).
