I have an internal group that exports Revit models to DWG and imports the DWG into Rhino to conduct acoustic analyses within the room(s). I had hoped Pollination could speed up this process (RVT to HBJSON to 3dm [using a .gh script]) since the effort to manually cleanup the 3D DWG in Rhino is pretty extensive. However, I’m struggling with editing Room3D objects after selecting “Full Volume” in the export - required to capture the sloped floor and ceiling geometry. This isn’t really a documented use case but wanted to see if there was a solution for exporting a semi-detailed model using the Revit plugin.
Hi @mdouglass,
I have helped a couple of cases like this. Here is the workflow that I recommend. You should not be using the full volume option since it doesn’t necessarily generate a clean geometry.
- Export the rooms as extruded rooms and clean them up in the Model Editor just like how you would export any other model.
- Export the sloped floor and ceiling as shade elements.
- Import both of them into Rhino and split the geometry of the extruded rooms with the floor geometry.
In my experience it works quite well, as long as you know how to use Rhino. Let me know if you would like me to help you with an example.
