Groups Acting Like Components

Morning People,

I’m using 'Pro…I’ve created a steel beam, and made a group out of it. I have copied it 5 times and I need to add different ranges of openings in each one. When I select one, all of them are highlighted in the Outliner Panel. This seems to happen until I right click and choose to edit…I don’t need to do anything more than this, just choose edit. This seems to force the issue to correct. I don’t think I’m doing anything different to what I normally do…am I wrong, or is there an issue (known or unknown)…

Always been that way, copied groups become unique as soon as you edit.

Ah…ok…I thought that only applied to Components…thanks for the reply.

…I’m confusing my self now…
…I get now that I’ve thought it through…thanks again…
