AppliCAD

AppliCAD is a no-cost 3D CAD program used for mechanical part design, supporting parametric modeling. Users can sketch 2D profiles, then extrude or revolve into 3D objects. A constraints system ensures design accuracy, automatically adjusting dependent dimensions. The interface includes standard geometric primitives like cubes, cylinders, and fillets. AppliCAD supports exporting to popular file formats (STL, OBJ). The community-driven library has pre-made parts. Suited for hobbyists or students wanting parametric control, AppliCAD offers a stable, open approach without monthly fees.
