Welcome to FreeCAD

FreeCAD is a powerful, open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows users to easily modify designs by going back into their model history and changing parameters.

Brief History

Developed by a community of passionate developers and users, FreeCAD’s open-source nature means it is continuously evolving. It began in 2002 and has grown to be a dependable tool in engineering, architecture, and product design.

Exploring the Interface

Take a moment to open FreeCAD and familiarize yourself with the interface. Notice the different workspaces tailored to various tasks.


FreeCAD Workspaces

Workspaces are collections of tools and commands that are grouped together for specific tasks. For example, the Part Design workspace is used for creating mechanical parts. Choose the ‘Part Design’ workspace and explore the tools available.
