  • Parametric geometry, meshing and visualization in one platform
  • Interpolates fields between different meshes
  • Regular public releases from CEA, EDF and OPEN CASCADE
  • Base for domain-specific simulation applications
  • Parametric: change a dimension and the model updates through its history
  • Sketch constrained 2D geometry and build 3D objects on top of it
All 5 strengths
  • Parametric: change a dimension and the model updates through its history
  • Sketch constrained 2D geometry and build 3D objects on top of it
  • Produces dimensioned production drawings from the 3D model
  • Separate workbenches for product design, mechanical engineering, architecture, FEM and CAM
  • Broad Python API for scripting and custom tools
  • Specialised for simulation work rather than general design
  • Steep learning curve for newcomers to meshing and simulation
  • Workbenches vary a lot in polish and consistency
  • CAD concepts plus FreeCAD’s own conventions make for a long learning curve
