Best Free Alternatives to AutoCAD
Updated 3 October 2026 · 3 programs compared
AutoCAD is the industry standard for technical drawings, but it is sold only as a subscription, which is expensive for students, hobbyists and small offices. These free programs cover the most common needs: precise 2D drafting with layers and dimensions, and full parametric 3D modelling. All three run on Windows, Mac and Linux and work with DXF files, which AutoCAD opens too.
Quick answer
Comparison at a glance
FreeCAD
The most complete free CAD program: parametric 3D modelling where changing a dimension updates the whole model, plus 2D technical drawings, architecture (BIM), analysis and CAM. Ideal if you need more than flat drawings.
Good
- Powerful parametric 3D modelling
- Many workbenches for different fields
- Free for commercial use
Keep in mind
- Takes time to learn
- DWG needs the free ODA File Converter
LibreCAD
A light, free 2D CAD program with layers, blocks and object snaps that AutoCAD users recognise quickly. It opens DWG files, saves DXF and exports PDF and SVG.
Good
