Having recently gone though the very tedious process of building a grid-like hanging structure over a whole theatre, so it could hang lights, report location etc, it would be a huge step forward if you would allow lines imported from a CAD program to auto-magically become hanging pipe structures.
WYSIWYG has had this feature since at least R26 (about 2011).

Theatres that have this kind of configuration and structure are common where I'm from, and I am not wanting to go through this again....
