Parametric & Surface Modeling

Rhino, SolidWorks, Fusion 360, CATIA, FreeCAD, AutoCAD 3D — all driven by the same sketch-to-solid pipeline and assembly constraint system.

Assemblies, Mates & Multibody Dynamics

Static mates are constraints. Real motion needs mass, inertia, and a dynamics solver — the same distinction as SolidWorks Motion versus a plain assembly.
