Everytime I add this single bolt to an assembly the BOM show a quantity of 4. My assembly contains 4 bolts so the BOM says 16. I took the part and made a new assembly, created a BOM and it says qty = 4. Therfore it seems the problem is with the part itself (that I inherited). I can easily redraw it but where's the fun in that?
Thanks,
Doug
The part may have a BOM Quantity set. You can check that in the custom properties. This may even be configuration specific.
