Hi Jeff, that's cool that you're back messing with the beta, I hope it can stick! :)

And yeah that particular stuff that you're building is very not like traditional semi-box-like architetural forms like sketchup is really designed to work with - a NURBS modeler is a way better fit for that kind of geometry. Pretty much a 100% perfect fit really with the kind of broadly curved profile-driven geometry that you have there. There's so many tools that will directly apply to that kind of construction - sweep, blend, offset, ... - and for construction it should also be a really big advantage to have a sort of ideal master model that can then be cut up in different ways as you need.

When you try to do that with a bunch of lines and facets you're kind of fixing a sort of cut up pattern directly in the base design instead of being able to create an idealized reference design...

Your shapes there just do not fundamentally resemble a box or a prism type shape, which is what sketchup is totally oriented around producing.
