Thanks for all the suggestions. You guys are a really great group!
Yes, it would be ideal to keep the model live and have all changes viewable throughout the model/plan. The orthographic view kind-of works, but there seems to be no way of showing the electrical connections. Which defeats the point of creating a RCP... at least the way I need to. I think both copying the plan or adding pony walls may solve the problem.. but but with their own set of issues. Obviously copying the plan requires twice the work. Going back and forth between two plans. But could work, if that is part of the work flow you are use to, like one would be if using AutoCad. Maybe pony walls would work... if I can assign them to their own layer that can be disabled in 3d views as well as other plan views. I assume that would be an easy fix. But I'm sure I would have be aware of some other details like materials lists and other dependents.
Anyway, Thank you.
