Hey!
Lately, we have been trying to figure out a way to import our assets into Revit but have failed to come up with any useful solution. Blender supports export to .OBJ file that can be imported into Revit, but it seems that whole file with multiple assets will be merged into a single object and no textures will be imported. I am currently not aware if there is a workflow to import Blender mesh data into Revit.
Ability to import our assets in Revit would certainly be beneficial for our users, if we find a way to make it work we will let you know!
