Rhinoceros 3d + Grasshopper + Rhino.Inside®.Revit
New: 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.
Python and C# Scripting: Rhino.Inside®.Revit provides a translation API to allow 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.
