FreeCAD for macOS is a powerful, open-source parametric 3-D modeler used for everything from product styling and car-part design to full building layouts. The interface is clean, supports both Traditional and Simplified Chinese, and opens/edits/saves more than 100 CAD formats—STEP, IGES, STL, DXF, IFC, OBJ, SVG, DAE and many more—so files from other programs drop straight in. Completely free for life, it handles mechanical, architectural and furniture workflows, doubles as a simulation sandbox, and ships with an integrated learning hub.
Feature Highlights
1. Build anything—free and parametric
Change a dimension in the history tree and the whole model updates automatically, making iteration effortless.
2. 2D ⇄ 3D workflow
Sketch constrained 2D profiles, then extrude, revolve or loft to solids; extract 2D drawings ready for production.
3. Cross-platform & data-friendly
Runs identically on Windows, macOS (Intel & Apple Silicon) and Linux; reads/writes open standards so it slots into any pipeline.
4. Purpose-ready workspaces
Dedicated benches for Part Design, Architecture (BIM), FEM, CFD, CAM/Path, Robot simulation and Geodata—hobbyist to professional.
5. Ever-growing toolbox
Modern FEA, experimental CFD, BIM, CAM tool-paths, robot kinematics and Python scripting give you room to explore far beyond vanilla modeling.
