How to trim three curves by each other?

The idea was to create a planar surface that’s bigger then the bounding box of the curves, so I get the bb, polyline the corners, then scale it up a bit…

I was puzzled because, isn’t it easier/faster/simpler to just use the bounding box create a brep.face with it then split the face. Why the scale?

I am also trying to figure out how to create a brep.face by creating a patch from the curves, but that’s insanely confusing. I’ll create another thread because that is a huge topic on its own.
