FreeCAD vs SketchUp

FreeCAD and SketchUp are both 3D and CAD software. FreeCAD is open source under LGPL-2.1, with 35k GitHub stars. SketchUp is a commercial product from Trimble Inc.

Which to pick

Pick FreeCAD when
Engineers, makers or small firms need free parametric CAD without SolidWorks or Fusion licences.
Pick SketchUp when
Architects, builders or designers need quick 3D concept models rather than full engineering CAD.

Side by side

What it does

A parametric 3D CAD modeller for mechanical parts, architecture (BIM), FEM analysis, CAM and 3D printing, built on OpenCascade with Python scripting.

Easy-to-learn 3D modelling for architecture, interiors, woodworking and landscape design, with a large model warehouse.

Watch out

Steeper learning curve and rougher edges than commercial CAD, though version 1.x fixed many long-standing issues.

Subscription only now, and precise engineering or construction documentation needs other tools.
