FreeCAD

This release is intended for developers and users interested in the cutting edge of FreeCAD development and is not recommended for production use.

What is FreeCAD?

FreeCAD is an open-source, general-purpose parametric 3D modeler widely used for computer-aided design (CAD), 3D modeling, and technical drawing. It supports feature-based modeling, allowing users to create and modify complex 3D models with a history-based approach. FreeCAD is popular among engineers, designers, and hobbyists who require a flexible and extensible tool for creating 3D objects, 2D drawings, bills of materials (BOMs), and revision tracking.

About the Weekly Development Builds

The FreeCAD project regularly publishes weekly development builds, which provide early access to the latest bugfixes, regression corrections, and recently implemented features. These builds are intended for testing and feedback purposes and are not recommended for use in production environments due to their experimental nature.
