ArchiCad have some timeproblems and memoryissues with complex large polygon objects, how shall we build our objects for making it so easy as possible for ArchiCad to handle?
It would be nice to have ability to check if you are in rendermode or in 3d mode, then you could have the fine model in rendermode and the simplier one in normal 3d mode.
But I don't think I could choose between this 2 modes.
