  • Real parametric constraint solving, so dimensions drive the model
  • Exports STL, STEP and DXF for 3D printing and machining
  • A script is a design, so parameterised objects and version control come for free
  • Constructive solid geometry and 2D extrusion, aimed squarely at CAD rather than art
  • The interface is bare and the workflow unlike mainstream CAD packages
  • Not suited to large or highly complex assemblies
  • The last tagged stable release is 2021.01, so in practice people run development snapshots
  • Not an interactive modeller: you cannot click and drag geometry
