Sometimes you need a placeholder for consumables, or other items that you don't model so that they show up on your BOM. This macro creates a little part; A rectangle with a part number on it's face, and adds 3 custom properties to it: Part No., Author, and BOM_Description.You can then insert it into your assembly, and make it virtual, so you have something to Fill in your BOM for those odds and ends.You can edit the macro to rename the fields to match your BOM structure.
