How to break reference

[CAD_user]

In an assembly, I made a copy of surfaces, from another part. Now I want to break the dependency to the original part.

How I can do this?

Take a look at this thread:  https://community.ptc.com/t5/Part-Modeling/Make-Surface-Copy-Independent-Creo-2-0/m-p/588930

I don't have the option to back up references available within the copy.

I don't have also Windchill...

The key is to collapse the copied surface(s) into the independent geometry feature.  Watch this video:

Ok. Fine.

and if i don't have the command available?

[TomU]

You can't pick collapse until the independent geometry feature exists first.  You also have to select both of the features together before you can pick collapse.

Sorry, but I still don't found how to do it. I select the copy, but the collapse, isn't available. So how can I create the independent feature?

[TomU]

Video is working now.  Watch it and see if it helps.  If for some reason you can't create an independent geometry feature, you could probably import a STEP file (of anything), delete all the stuff inside the import, and then collapse your surface into that feature.
