Create biggest contour from coplanar curves (like curve boolean)

[huskenazy]

Hi all,
I have a brep consisting of 2 continuous surfaces, not coplanar. Originally I had 2 separate surfaces, which is why I got a brep, and not a new unique surface.

Now I want to get, instead of this brep, a surface that I have:
1.the lower edge is the segment connecting the two lower edges of the two non-coplanar surfaces
2.as plane, the plane aligned with the edge.

Then i Project the edges on the plane i Found

So far everything is ok.
Now, How can i get the biggest contour from coplanar curves, to get a planar surface from it? (something like curve boolean in Rhino).
I tried to join the curves in various ways but I can’t figure out how to do it.
This is my attempt with internalise curves.

Thank you!

I’m not sure if i understood exactly which edges you want to form your projecting plane. This should be what you are after, i mainly used ‘Curve Curve intersect’ and ‘Sub-Curve’ which is a really awesome component i highly recommend learning and using i have a lot of fun with it

There is also Clipper Plug - IN which i see recommended here alot whenever it comes to curve boolean operations but i never used it so i don’t know how useful it would be

Hi @lando.schumpich,
thank you very much, I look immediately.
I need this definition for the cluster for the broader definition I have been working on these days. Take a look.

Hi @PeterFotiadis As for the floors that protruded, I adopted your advice, and I resized them, so the result is simpler and more aesthetically beautiful. As for the shape of the roof, it is long enough to explain. Let’s say that the project required required a particular form, derived from the study of a concept of our choice. In this case the language required tends more towards the contemporary blob trend, as you have defined it, than towards the “less is more” style of Mies Van Der Rohe (…

AHA I solved.

You gave me the idea with your definition.
I always need lowest edges of the 2 surfaces, so i need the first part of my definition to get the plane. I solved simply connecting to G input of Project the Brep B instead of the edges from output E of De Brep .
Then i used brep join + merge faces that i higly recommend too.
