Help with IES / SketchUp

[dale]

Have any of you had any experience with developing models that work within the IES VE software.
I'm trying to adapt the model, but have had no luck so far getting a complete verification of the rooms.
We have virtually given up on the thick wall technique,as it has produced no results.
In the thin wall technique, I have made all the volumes solids, verified their integrity, and exploded and erased one of the walls between adjacent rooms that were originally created to verify the volumes.

I'm giving it a try here, while the fellow I'm working with is trying the IES Forums.
Any advice would be appreciated.
