FreeCAD review

FreeCAD is the strongest offline option for precise, dimensioned parts at no cost. It is a parametric modeler built on the Open CASCADE geometry kernel, so you sketch constrained 2D shapes, turn them into solids and change any earlier parameter later. Version 1.0 added a built-in assembly workbench and merged architecture tools into a BIM workbench, and the current stable release is 1.1 from March 2026. Beyond modeling, it includes Finite Element Analysis, CAM and CNC paths, 2D drawings and a large add-on ecosystem, and it reads and writes STEP, IGES, STL, OBJ, DXF, SVG and IFC among others. The FreeCAD site promises no sign-up, no paywall and no restrictions, and your files stay on your computer. The cost is learning time: tools are split across workbenches, and the first sessions feel harder than in Onshape. For makers who want private files and no account, that effort pays off.

Who it is for

Makers and students who want desktop parametric CAD with no account, no paywall and no usage limits.
