Rhino 3D (Rhinoceros) is a commercial NURBS and SubD modeling application from Robert McNeel & Associates, used across architecture, product design, jewelry, marine and engineering. The current release, Rhino 8, runs on Windows and macOS and ships with the Grasshopper visual programming environment — try it free for 90 days or buy a perpetual licence.
Unlike subscription CAD tools, Rhino is sold as a one-time perpetual licence with no recurring fee. It reads and writes the open .3dm format and imports and exports DWG/DXF, STEP, IGES, OBJ, STL and dozens of other formats, so it fits into almost any pipeline. Its accuracy and free-form surfacing make it a standard in jewelry, marine, footwear, architecture and industrial design, and a library of more than 1,500 plug-ins on food4Rhino extends it into rendering, animation, engineering analysis and fabrication. This guide covers how to download Rhino 8, start the free trial, check system requirements, compare pricing, and see what is new — with every download and purchase completed on the official rhino3d.com.
