I ran into an issue trying to use the toolbox and was wondering if anyone had any ideas on how to handle this. When we set up our library we used "Part Number" as a custom property in all of our parts and set up our BOM's accordingly. I am now trying to use the toolbox for fasteners and having a problem entering in "Part Number" as a custom property. I can add other columns without any issue. SW is giving me an error message because there is already a column called "Part Number" however, that is tied to the SW property and not the custom property. As a result, the part number does not show up in our BOM. I need to figure out a way that I can put our part number in the toolbox field and tie it to the "Part Number" custom property. Does anyone have any ideas?
