Hi Dave R.

Thanks for your answer.

1º - I already try it, but I miss how can I build the inside frame structure for support the dome. Try to think like "Gothic Arch" and its timber frames structures.

I need to build some structure for support that shape. And I need to show it in SU model.

if you need I post some images of the project, please ask, so you can see for your self better what I pretend to do.
