Parity score43%
  1. FreeCAD, Parametric solid and surface modeling: Part Design and Sketcher build solids with a feature tree
  2. FreeCAD, Assemblies and joints: A built-in Assembly workbench with fewer joint types
  3. FreeCAD, 2D drawings from models: TechDraw makes dimensioned sheets; the tools are less polished
  4. FreeCAD, CAM toolpaths for CNC machining: The CAM workbench covers 2.5D and 3-axis toolpaths with a manual setup
  5. FreeCAD, Simulation (FEA): The FEM workbench runs CalculiX and other solvers; setup is manual
  6. FreeCAD, Electronics and PCB design: No PCB design; KiCad is the usual companion
  7. FreeCAD, Cloud data management and sharing: Files are local; share them with Git or a file service

  2. FreeCAD, .step: Solid geometry exchange
  3. FreeCAD, .stl: Mesh format
  4. FreeCAD, .dxf: 2D geometry, layers and text carry over; blocks and dimensions can lose detail
