pub fn register(r: Registry) -> GeopResult<Registry>Expand description
Adds what assemblies offer an editor to r: placing parts and patterns
of them, parts derived from others and mirrored, the STL of a part with its placed parts and the URDF of its
mechanism, how placed parts are drawn, the joints panel, the drag tool,
what settles the program’s state after every edit, and the examples of
assemblies.
