Stuff Billings window & door installers ask before they sign up
Does this respect MT code, or do I have to re-cut every quantity?
The takeoff doesn't pull a permit for you — that's still on whoever holds the Contractor Registration — but the assemblies match what MT inspectors look for.
How do you handle counting and sizing all openings?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For energy work in Billings, the typical correction is one or two assemblies — not redoing the whole thing.
What about site conditions?
Build the local condition into your assembly defaults once, and it carries forward to every Billings bid afterward.
