We can create a schedule of wall lengths, and use that calculated total to estimate wall sheathing and framing. You can then estimate wall finishes,
and the room information can give you ceiling and floor areas, even without modeled ceilings.
With a highly developed model, we can give exact SqFt and even volume of materials calcs of every wall, window ceiling and floor etc. etc. broken out
by type, and use that to break out in wall plywood blocking, gyp bd, coverage of tile adhesive, etc, and aggregate room finishes to overall project
totals for specific finishes.
