This has been one of my suggestions for almost a decade....all the software is doing is setting a reference point. AC's default seems to be the bottom of the wall, however one could tweak the code and enable the setting of the reference to slab, or story or whatever.
Should've been done a while back....& I'm amazed with all of the Beta testing, this has never come up.
While I agree to a point that we should design a building the way it's built, I don't really design a building by constructing/framing each wall separately by laying it down and measuring from the sill. The analogy breaks down here and I need to work with an improvement that works with the way I design.
This has been an easy fix in the otherwise unglamorous field of construction documentation.
Still productive on 7.
