When creating my Material Buy lists, I noticed the programs use of 2" x 4" - 7'-8 5/8" for both 2x4 and 2x6 items. The finished ceiling height in the walk out basement is 9' 1 1/2". I see the exterior wall studs using (19) 2" x 6" - 10'-0" and the interior wall studs using (85) 2" x 4" - 10'-0". Is the program using the 7'-8 5/8" pre-cut length boards as a more efficient use of materials for use of shorter cuts? It would be beneficial to be able to identify an item in the 3D view by the ID (F1, F2...) used in the material lists. I have asked about this previously and I was told it is not possible. Maybe in the full Cheif Architect program, it is possible. Anyway, clicking on each item in the 3D framing view and comparing it to the Buy & Cut lists is a pretty tedious exercise to try to figure out where/why these 7'-8 5/8" lengths in 2x4 and 2x6 are being used. Since I am only a DIYer and not a professional construction type, a little insight would be fabulous as I would like to start ordering lumber. I have searched the KBS, manuals, and now the forum for information concerning the subtle specifics of naming & length theory but haven't come across anything. Thanks much!
