Short on time? Here's the quick answer

We've tested both tools. Here's who should pick what:

Solvespace

Parametric 2D/3D CAD for modeling, assembly, and mechanism design.

Best for you if:

  • • Free parametric 2D/3D CAD software.
  • • Supports modeling, assembly, and mechanism design.

OpenSCAD

The programmer's solid 3D CAD modeller for creating precise 3D objects.

Best for you if:

  • • Creates solid 3D CAD models using a script-based approach.
  • • Focuses on technical design for machine parts, not artistic modeling.
