Compound

Compound is an explicit multi-shape projection wrapper.

SimpleCADAPI 2.0 beta keeps integrated modeling centered on single Solid results, but product-level Assembly workflows can be projected into a flattened Compound with make_compound_from_assembly_rcompound(...).

The stable public geometry wrapper surface is:

• Vertex
• Edge
• Wire
• Face
• Solid
• Compound

Use Compound when a workflow intentionally needs a flattened geometry projection. Do not use it as a substitute for Assembly product structure.

For normal part modeling, keep using Solid as the body-level geometry. A single-body Part wraps exactly one Solid.
