Mesh to Solid — Turns a mesh into a Solid whose value is the exact signed distance to the mesh's triangles.
Quad Mesh to CAD Body — Turns a quad mesh into a watertight CAD body: one smooth B-spline patch per quad (a Catmull-Clark surface; a mostly-quad mesh is refined once first), with the creases from Triangles to Quads as sharp edges and a tangent break next to irregular points.
Solid to Delaunay Mesh — Turns a Solid into a watertight triangle mesh by adaptive Delaunay refinement: large triangles on flat areas, small ones where the surface curves, sharp edges kept exact.
Solid to Mesh — Turns a bounded Solid into a triangle mesh by sampling it on a uniform grid (cell = tolerance/2), so nothing at or above the tolerance is missed.
