Selecting outer surface

Hi Guys,

Hoping someone might be able to help. This BREP that i have produced, i am planning on turning into a waffle, seat-like structure for a pavilion. I’m not trying to create a roof and i want to create a panelised surface that only applies to the surface above the brep and on the outside. I’ve tried to deconstruct the brep, but the way that it is dividing the surfaces is providing me with areas that aren’t great. Can someone please help me to extract the surface from the Brep that is the top and outer left hand side? Thanks.Simon Dwyer (15.1 KB)
