If I want to add a blueprint to an already existing building or to a part of a building (ex. window composed from 3 other items) - is this possible? If yes: how?
I add a blueprint, it will be a "group". Then I select this group and copy it - and then everything stops, because if I select the other group, my previous selected copy is lost.
