I have a top assembly with many subassemblies and thousands of custom made bolts in them.

I need to replace all the bolts with new ones (many instances of the same bolt). I am doing this because we have created a new fastener library and I have to update the assy. with the new components.

So what I did is I named the mating surfaces of the old and the new bolts in the same way using the "Entity Property". I hoped that during the Replace Component operation I wouldn't get errors or need to re-mate my new bolts. It didn't work. The reason is that the original mates were done before I named the surfaces.

Do you know of a way to update the mates in assembly so they refer to the names from the "Entity Property" and not the automatically assigned internal ID?

Thanks in advance for your help.
