I am running SW 2025 sp5. I use envelope parts as a way to pass important refs from one assembly to another. I will add a part to an assembly and call it "refs for whatever". I will then copy all the faces I need to use with a surface copy. In the past all the surfaces would show in the new assembly that I need to work on. For some reason when I turn the part to an envelope everything is hidden? No matter what I do it will never show the surfaces in the assembly file.  I even tested with a solid extrude and it did not show. They all show up in the envelope part in I open it solo. All the features are there. If I go back to the assembly and change the part to not be an envelope part, then everything shows up.

I am missing something that changed in 2025. I have used the RMB "Show all envelopes" with no luck.
