I have several different versions of the same design, all different sizes dependent on the application. All of them should be built the same, look the same etc. So bom item 1 on the -1 should be the same as the -2 etc, etc. I am replacing a partial quantity of a fastener on all assys. When I replace them in the solid (the fastener is part of a design table), they are now showing up on the BoM as different position numbers. What is the simplest way to move them to all match?
