Rhino.Inside is an open source Rhino WIP project which allows Rhino and Grasshopper to run inside other 64-bit Windows applications such as Revit, AutoCAD, etc.

Expired evaluations are great for learning Rhino or viewing Rhino and other file formats. Technically there is the fourth entity – the Point entity, but it doesn’t really count, since it’s not used for modeling, but mostly as a reference, or a marker. There are three fundamental entities that comprise the Rhino – the Curve, the Surface and the Solid. The working principle in Rhino is somewhat different from most 3D packages and more like a CAD program. NURBS (Non-Uniform Rational B-Spline) is based on the definition of 3D surfaces with mathematical formulas (splines).

Rhino gives emphasis to model’s precision and therefore uses NURBS technique. Rhino is not intended for video industry and effects where high precision is not required. Rhino is accurate as CAD, and useful when you create model for visualization and presentation, but not just for production or simulation. Rhino is the 3D-modeling software used for mathematically precise modeling of products ranging from jewelry and furniture to architecture.
