James,

I downloaded your part 6 of "Spread Sheets" and would like to know if your instructions will allow for the product to inherit "parametric capabilities.?

I built this in Foundation" using "pick corners". for sub insert's. It was built at 48" wide and as you see the carcass grows, with width change  and not the inserts. I remember a comment that was made about "pick corners" not holding formulas or parametric capabilities; as show in this attachment of 62" wide.
