Rhino is a surface modeling application with an incredibly fast and accurate freeform geometry engine that also supports meshes and point clouds. Rhino supports more that 40+ file formats, making it a great interoperability tool. It is easy to learn, very customizable, extensible, and has a very strong third-party ecosystem with over a thousand add-ons providing lots of additional capabilities
Grasshopper is a visual programming environment tightly integrated with Rhino’s 3d modeling tools. Grasshopper requires no knowledge of programming or scripting, but still allows designers to build generative forms from the simple to the awe-inspiring. Grasshopper also has a very rich add-on library
Rhino.Inside.Revit adds over 300 Revit-aware components to Grasshopper that can query, modify, analyze, and create native Revit elements. More components are added in each release to support more Revit native types
Rhino.Inside.Revit provides translation API to allow creating custom conversion workflows between your Revit data and Rhino geometry and metadata. This includes an advanced geometry conversion API to safely translate advanced Rhino shapes into Revit. The API is easily accessible from Grasshopper's Python or C# scripting components
