Rhinoceros 3D

What hackers pick instead

• FreeCADA free, open-source parametric CAD modeler that has improved rapidly and can replace Fusion 360 for many hobby users, though its UI remains complex and hard to learn.199recommend
• OpenSCADA free CAD tool where you describe models in code, loved for precise, parametric, version-controllable designs and LLM-friendliness; critics note missing fillets/chamfers and math-heavy modeling.173recommend
• OnshapeBrowser-based parametric CAD that is easy to learn, runs on any machine and has multi-user editing; the free tier makes designs public.65recommend
• Autodesk Fusion 360Recommended for fast, capable parametric 3D modeling, with a free hobbyist license and an easy learning curve. The most common caveat is that the free license could be changed or withdrawn, and Autodesk pushes paid upgrades.60recommend
• SolveSpaceFree, fast, lightweight parametric CAD praised for simple sketching and quick learning; critics say it lacks features and its booleans often fail.37recommend

1. Rhino has amazing "BlendCrv" and "BlendSrf" commands that allow you to combine curvatures between the two curves / surfaces being blended.

2. Arguably the best modelling (parametric, manual, or SDK) ergonomics when it comes to, from my experience, early stage aec workflows.

3. Rhino is not without its drawbacks. It is time consuming but it's worth it because, as a sales tool, it wins every time.
