So I'm trying to create a "raw materials" BOM in my drawings for Procurement to accurately cost the build. I had found a forum post that addressed my issue (https://forum.solidworks.com/thread/105751#comment-540196 ) but now I'm finding a variable that i never set, but it's the exact one i need! It is called "SW-SurfaceArea". and it is calculating all the surfaces and their areas. Problem is, when I try to reference it in the BOM table, it isn't available Not sure how to go about this. I'm honestly somewhat new to the software but I have a fairly good grip on it. The attached file shows all the variables that "came out of nowhere" that I cannot reference in the BOM. I appreciate any help!
