while that may be true. In this specific example, Revit is successfully outputting the geometry for use in a Revit API context, (Autodesk.Revit.DB.Solid).
Where this workflow is actually falling apart is in the Dynamo side with the ToProtoType converters, (Solid converters are here).
@GavinCrump - I realize it is the “cool” thing to do to bash Revit and say, “RHiNo iS bETteR”, which I can agree with in a lot of instances. But in this case, and I mean this respectfully, you’re assumption re: Revit not handling the geometry is simply incorrect, (because once again, this is happening on the Dynamo conversion portion).
The best thing OP can do is first, supply a sample file here for us to help further (we don’t even know the Revit version at this point), then, open a Github Issue, supply the sample Revit file and the team can refine/work on the converters for solids regarding Dynamo geometry. This is how Dynamo becomes better.
