We're doing a lot of multifamily work, and using groups to arrange units. The biggest challenge we have is with hosted family components (tubs, wall cabinets, closet rods, etc). They don't really behave consistently in groups. Our main Cad guy recommended that we just redesign all the components we need as non-hosted. Question one - is there any real drawback? Besides having to align the edge of a tub to a wall manually (as you do with a toilet or base cabinet) i don't see any benefit. And 2- is there an easy way to change them, like a switch? It looks like the protocol is to open the hosted family and copy the model over to a new non-hosted family. Not too bad, really.
