Getting polygroups back onto the merged subtool

Hi all,

I have a question:

I needed to attach/merge some polygroups. As I needed to split them into there own subtool. See my example. So i did a autogroups… then split the subtool., but then I have lost the polygroups ofcourse.

Is there some trick to get the polygroups back onto the model?

Would you need to use the history state?

Just wondering how you would do this :slight_smile:
