Understanding the materials list

[BACLLC]

Thank you David,

The "28 1/16" value is an inventory of that wall type found in the model at that stated height) . . . ? can you better explain this comment ? . . . don't quite understand the 28 1/16" value and where it comes from, I don't recall a wall of that size, unless I do not understand you.

I knew I could count on your experience to better help me understand the points made. I will review "my design" and then have another look at the materials listing.
