Hi @jjansman, thanks for posting on the forum 
Yes, this is how CAD mode operates. I’ll try to summarize how it works in respect to changes in the geometry:
- When you edit a geometry in CAD mode, it and all of it’s copies will experience that change.
- If you run an operation and just click on exit, it will be saved within CAD mode but the geometry in the simulation tree won’t experience any change. If you go back to CAD mode, the operation will still be there though.
- If you delete an operation, all of the operations done after that one will be deleted.
A workaround for editing different geometries is to upload the original one multiple times, so that each one should be changed on it’s own for the alterations to be applied in CAD mode.
Does that help?
Best,
Igor
