It is useful to create groups when copying similar bathroom plumbing designs up a building. Not only does one have control over the design through the editing of the definition, but one can reuse the groups in other projects.

There are some items of interest.

There is a bit of an issue when adding pipes and fitting to a group definition: one first must remove the elements one is editing and then add them to the group after editing again.

A collar is put on the pipe to connect it to any group. If these are not required in schedules, plans must be made to exclude them.

Some difficulty was experienced when mirroring and copying groups as well, although with a bit of editing tight fits these were eliminated for the larger part.
