“Free CAD” can mean very different things. For business use, the licence matters just as much as the feature list.
FreeCAD is a capable zero-licence-cost option for parametric solid modelling, technical drawings and CAM-oriented workflows. Its interface and workbench model can demand more learning than some commercial alternatives.
Visit FreeCAD →Onshape's Free plan is intended for non-commercial projects and stores documents publicly. Onshape's paid plans add commercial-use rights and private storage. That makes the free plan excellent for learning and open/public projects, but not a no-cost route for creating proprietary commercial designs.
Always distinguish between a free trial, free personal/hobby tier, free education licence and a licence that permits commercial use. If you are designing something for a paying customer or a product your business intends to sell, verify that the licence covers that activity.
FreeCAD's current feature set includes parametric solid modelling, assemblies, drawings, STEP/IGES/STL/DXF exchange, CAM/CNC workflows and finite-element-analysis tooling. It is therefore much broader than a basic hobby modeller, although workflow polish and interoperability should still be tested against your own files.
