Fit a B-spline surface through a grid of Z-heights.
Build a triangular face from 3 points. Returns null if degenerate. Used by importers, hull, roof, and surface builders.

Build a wire from a mix of edges and wires (uses Add_1 for edges, Add_2 for wires).
Remove all inner wires (holes) from a face. Returns a new face with only the outer boundary.
Sew triangular faces into a shell and convert to solid.
Build a triangulated surface from a height grid.
Add hole wires to an existing face.
