Join multiple groups while building?

[Saret]

Hi! first of all, sorry for my English, I´m not really used to write in English.
I´d like to know how can you mix multiple groups from one building while building, just in case you need to move everything toghether.
Thanks!

You can only connect non grid groups together, the items that do not have a yellow grid when placing. If you want to move everything with grid items, you will need to copy the entire building and make it into a blueprint and then place again. If your building exceeds 4000 pieces however, you will have to manually rebuild your building if you need to move it.
