Hi

I noticed today that if I build walls in a U-shape and calculate the materials, the exterior wall materials show up in the Siding Section, but if I put a porch between the U-Shaped section the walls within the U-Shaped section show up in the Wall Board Section  Making it a room changes where it calculates the material sections

i have been programming X12 the calculate my materials very accurately

Is this a glitch with X12 ?
