I have several sheet metal parts in a larger in context model and I do not want the PEM fasteners to be part of the larger BOM but I do want them in the BOM of each individual sheet metal part. So I saved all the sheet metal parts out as individual part files and added the PEM fasteners as derived parts. This is fine except the BOM does not reflect the PEM fasteners when creating a BOM table and drawing for each individual sheet metal part. It see the part file with derived parts as one part. What is a better way to do this.
