Sometimes, when I translate surfaces into walls, Revit will inform me that my surfaces are too complex to be translated. (Especially when I import the surfaces from Rhino) And my operation will fail. So I have some questions about the conceptual mass in Revit.
1. Does the wall translating tool accepts all kind of surfaces?
2. How to evaluate the complexity of a surface?
3. How to avoid the failure when I try to translate the surfaces into the components based on surfaces?
Should I pay attention to the generation of surfaces in other modelling tools?
Thank you in advance!!
