I'm new here and have been using revit for about 2 years now. I'm still having trouble understanding and creating wall types for exterior walls. Let me explain.
Exterior walls are made up, if you will, of the structure (drywall, 2x6 studs, insulation and sheathing) and the finish (EIFS, board and batten). I've tried building a wall with both the structure and the finish together, and modelling a 2 storey building where the wall would run from foundation to top of parapet. At times, if i have a material change say in the middle of the wall, it becomes problematic.
I've also tried building the "structure" (drywall, 2x6 studs, insulation and sheathing) from floor to floor and applying the finish from foundation to top of parapet and if there are any material changes i can cut out the finish and replace with new material without interupting the basic frame structure. But the problem with this method is if the building expands or contracts I would have to go around and change each wall. I makes it more cumbersom and I believe it doesn't exploit the power of a BIM 3D modeler. I might be doing something wrong here though (not constraining walls or should be building structure from foundation to top of parapet, etc)
Can I get a best practice or experience from others on how to tackle this issue? I basically construct the model as though I was physically "building" the building, i may be wrong though.
I welcome other peoples opinions on this.
