Is it possible to create an assembly to take off for example - walls (LF) wood base (LF) and ceilings (SF)? The first two are easy by using setting the assembly to lineal and making quantity 1 "=length" for the walls and wood base. It would really be great if I could figure out how to have the program calculate the ceiling area at the same time so that I don't have to take off the same room twice.
