I have a rhino file with 3d surfaces of different types modelled from data in grasshopper (grass, roads…). I would like to transfer these surfaces in revit as a topography with subregions.
I tried as directshapes but it gives me triangulated faces in revit (trimmed surfaces in rhino)
Then I tried to create the topography in revit from rhino (topography from points). It works but I have absolutely no idea if it is possible to create subregions from grasshopper. (or split it)
Has anyone worked on something similar ?
