BetaBetaBetaMakes elements the parts of a new assembly standing in their storey in their place. The parts keep their geometry and placement and stand in the model through it; removing the assembly removes them.
They must share one storey, or other part of the structure, and belong to no other assembly; openings cannot be parts.
