Graphite3D Free

Graphite3D Free is a parametric solid modeler featuring a robust constraint solver. It includes revolve, extrude sweeps, fillet/chamfer, and multi-part assemblies with constraints. A BOM tab updates as components are added. Graphite3D also manages revision history. Suited for hobby machinists or students wanting a zero-cost approach to building small mechanical assemblies, Graphite3D Free gives step-by-step parametric modeling plus a BOM output for production references.
