Alternatives to FreeCAD
Open source parametric CAD
FreeCAD ranks #9 of 13 in 3D modeling software, with an Alt Score of 50. It is licensed under LGPL-2.1, free and available on Windows, macOS and Linux. 10 of 10 checklist rows are verified against a public source.
Mechanical engineers, product designers, hobbyists, students, and architects who need to create precise 3D models of physical objects without paying for commercial CAD software.
A free, open-source parametric 3D modeler with constrained 2D sketching, solid modeling, and assembly tools organized into task-specific workbenches (Part Design, Sketcher, Assembly, FEM, BIM, CAM). It supports finite element analysis, CAM/CNC toolpaths, and import/export of standard formats like STEP, IGES, STL, and DXF. Because models are parametric, every feature is tracked in a history tree so dimensions and constraints can be edited later rather than rebuilt from scratch. Python scripting is available for automation and custom workbenches.
You sketch constrained 2D geometry, then use Part Design or Part workbench tools to turn sketches into 3D solids through operations like extrude, pad, pocket, and revolve. Because the model stays parametric, editing an earlier sketch or dimension automatically propagates changes through the rest of the feature tree, and finished models can be exported to CAD, 3D printing, or CAM formats.
