I'm working on creating an Excel based BOM template. Along with name, quantity, etc. it pulls some custom properties from the parts. Can I add formulas to my template and have them work in the BOM? For example, I'm pulling length and width dimensions from the part custom properties. I then want the table to simply multiply them to get area, but when I put the formula in the template, it's not showing up on my BOM. Any ideas how to make the formulas work?
