I'm a new user and I'm trying to model a factory with 4 different roof
heights. The 32 ft roof is over a freezer at minus 10 degrees F, and 3
other heights cover the office and different factory spaces. I don't see a
way of creating different roof heights. All I can think of is building 4
different buildings separately, but that creates a number of big problems
for the simulations. Any help offered will be greatly appreciated.
