FreeCAD drawing

FreeCAD

is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters 

Create your first model in FreeCAD v0.21.2 using the Part Design Workbench.

With FreeCAD 1.0, you’ll master feature-based modeling, where each design element builds upon the previous one in a structured history tree. This course is ideal for engineers, designers, and hobbyists who want to learn how to use Free CAD 1.0 effectively for real-world 3D modeling and parametric design
