Find all external faces of multiple adjacent brp

Grasshopper

Hi,

I would like to compute the external wall area of simplified building. Each part of the building is a separate brep. The thing is that I can’t solve the intersection between the different brep…

Does someone has an idea?

Without any files people will find it difficult to help you. With files they might still find it difficult, but at least then it’ll be because the problem itself is difficult.

Ok here it is, but I finally found a way to solve my case, so I share my results :wink:

Thanks
