Frequently Asked Questions
- Is FreeCAD good enough for professional mechanical design?
- FreeCAD has matured significantly and is now used in professional mechanical design, especially for small studios and startups that cannot justify SolidWorks or Fusion 360 subscriptions. The Part Design workbench is stable for parametric modeling, though the assembly workbench is still evolving.
- Blender vs FreeCAD for 3D modeling?
- They serve different purposes. FreeCAD is a parametric solid modeler (good for engineering, dimensions, constraints). Blender is a polygon mesh modeler (good for organic shapes, animation, rendering). Many users run both.
- Can I use free 3D CAD for commercial product design?
- FreeCAD, Blender, and OpenSCAD are all GPL or open-source licensed with no commercial-use restrictions. Fusion 360 Personal and Onshape Free are freemium but prohibit commercial use in their terms.
