what I really miss is in place editing skins of composite walls. something like with curtain wall, you press edit and then each wall skin would be treated as separate wall, which would make me able to define which skins should be connected together. or if needed one skin is finished earlier than the rest of the wall. after you are finished with editing you pres OK and then wall is again just a wall with custom geometry and with connections in model. now instead of doing that in model I have to go to worksheet to clean wall intersections.
