I have a bracket that is made up from three different pieces, a plate, a gusset and a shaft holder. these three pieces are then welded together. After the welding is completed we boar out the hole for the shaft and drill two holes for set screw. I create the last two steps of the part (boar for shaft and set screws) in the part assembly. when I create a mirror part of the bracket the shaft boar and the set screws do not carry over to the mirrored part. do I have to make the assembly into one part then do the last two steps. them mirror the part? If I have to create a part out of the assembly how do you do this? Any other suggestions on how you would do something like this is appreciated. Thanks Nathan
