Project Summary
QymCAD is a desktop parametric CAD for mechanical parts and assemblies: enclosures, brackets, mechanisms, work meant for 3D printing or CNC milling.
A sketch becomes a solid via extrude, revolve or sweep; the solid gets holes, fillets (including variable-radius), chamfers, a shell, patterns, and booleans. Threads are built from a real helical profile with run-outs, not just a decorative texture.
Parts come together into assemblies through joints - revolute, slider, rigid, and more - with an interference check.
The geometry is exact, B-rep, computed by the OpenCASCADE kernel - the same one FreeCAD runs on. Exchange via STEP, STL, DXF and SVG.
No subscription, no cloud, one project file. Open source under AGPL-3.0. Builds for Windows, Linux and macOS.
