  • Real parametric constraint solving, so dimensions drive the model
  • Exports STL, STEP and DXF for 3D printing and machining
  • Parametric: change a dimension and the model updates through its history
  • Sketch constrained 2D geometry and build 3D objects on top of it
  • The interface is bare and the workflow unlike mainstream CAD packages
  • Not suited to large or highly complex assemblies
  • Workbenches vary a lot in polish and consistency
  • CAD concepts plus FreeCAD’s own conventions make for a long learning curve
