I dont know which method is the right one. JoinGeometry?
It should work out as the solid.ByUnion in Dynamo nodes, but with the revit API, I dont want to use the solid.ByUnion cause the conversions and to use Dynamo nodes consume a lot of time (I tried out already and the code get really slow)
i want to join solids in Dynamo with the revit API and not with the Dynamo Nodes solid.ByUnion. The solids are for a clash detection. If there is not a method for that in the API, i will find other way
