- Open the 3D model in 3dsMax
- Export to STL
- Import the STL into MeshLab (File - Import Mesh)
- Export the mesh as an XYZ file (File - Export Mesh As...)
- This XYZ file can now be imported into Recap, or indexed by Revit into a PCG, or used in various other software tools
Note: You can also create STL files (steps 1 and 2) directly from Revit using the STL Exporter add-in.
Some of these tools were discussed at:
