Please could you help a novice SW user (me) with the following : How do i transpose a hole(s) position from one item to another. ie. I have a sheet steel panel with no holes in it. I have inserted it into an assembly drawing, and i want to `pick up' the tapped hole positions which are in the mating parts of the assembly. These tapped hole positions are underneath the sheet steel panel. I need to transpose these positions to enable me to put the clearance holes into my sheet steel panel. I hope that makes sense ! I have tried inserting a simple hole but i don't seem to be able to add a concentric relation to the tapped hole in the mating part. SW tells me `please select from two different sub-assemblies'
