Hey there,
I have created some custom families for DIN 934 nut. The main reason is the material. I have DIN 934 A2 and A4 families. By default, their Part Numbers do not have any explicit information so them are identical. This causes an issue in the Parts List, because Inventor confuses them and show them at the same line, with the same Part Number and with the Word "Varies" in description. Now, if I go to family table and enter an expression; "DIN 934 - "A4 " & {DESIGNATION}, then Bolted Connection Wizard is not able to find DIN 934 A4 (for example) family in the DIN section.
Thanks.
