Greetings all, I’m new to the world of CAD programs. Will someone tell me how to unlock bodies tied by a union?

Your help will be greatly appreciated.,

You can only undo the union. And then not after you close the app and start it again, usually. When using unions, or other complex operation on a object or objects that took time to make it is a pretty good idea to make a copies and hide them before you do it.

This is where direct modeling has a “gotcha”.

Thanks for the information. I will make sure to keep a non-unioned copy from now on!
