Spreadsheet-cad.com seems like a tremendous idea. What is the demo you're speaking of? I see examples of a structural angle member and a cylinder with some API attached. Izzat it?

Would love to have some attack made by the spreadsheet-cad guys (or some API fiend) making it possible to edit weldment cut lists in a design table. What would you think the interest level may be. Anyone using weldments extensively?
