Builds Generative Shape Design wireframe and surfaces, including multi-section surfaces, sweeps, fills, blends, joins and trims.
Adds assembly constraints, measures distance, inertia and bounding boxes, and edits parameters, formulas and design tables.
Exports STEP, IGES, STL, 3DXML and VRML, and creates drawings with generative views (experimental).
Can run in HTTP mode with a token on the CATIA PC so the agent can sit on a Mac or another machine.

Windows only, because it uses CATIA's COM automation.
3DEXPERIENCE CATIA is not supported; the author lists it as a wanted contribution.
Avoid switching the active document while a tool call is running.
