Transformation from Triangles in parallel Planes to closed Brep wont work

[arbeit]

I’m struggling with the transformation from two similar Triangles in parallel Planes to a closed Brep
I’m trying to represent the process of making a 3D triangulated Wall out of Plywood in Grasshopper to get a template to use on other Plywood Walls Designs. In the Design I will get one Mesh or Polysurface. Till now I managed to define the Base Surface and its projected Surface. Now I cant figure out how to make a closed Brep out of these two Similar Triangles in parallel Planes. The goal is to get the exact Plywood Panels Measurements. Especially the edges angel between two panels. For they are of the dividing angel of the Normals of the two panels.

Adding Pictures of the Grasshopper Algorithm, the Mesh Input Wall, the Point at which I am and a Detail with scribbles, as well as the Process Grashopper File and an internalised Grasshopper File of the Point I got stuck.

your gh file with the process is very readable and well described
about going Closed Breps, you can Loft the boundary curves of each surface, something like this:

Thank you very much. Gone shopping for the weekend after which I’m following your lead. I’m excited.

Back from shopping, plowed through your algorithm and it worked like a charm. On the way found some other issue not related to this problem. And my problem was and still is my basic knowledge of the loft component. I had similar solutions but they had twisted surfaces. So now my next task is to research the loft component to get a more profound understanding of this function.
Thanks again @inno for your brainpower on my problem, it helps a lot.
