From Closed Brep to Invalid Mesh

Hello everyone,
I have the problem that an invalid mesh is created from a closed brep.
My goal in the Grasshopper code is to create ribs to stabilize, for this I used the contour component to create a curve in the shape of the ribs, offset the curve slightly and then between the two curves I created a surface (red in the screenshot). I then simply extruded the surface. I wanted to connect the extruded brep to the original body (green in the screenshot) so i converted the rib structure into a mesh, but I keep getting an invalid mesh, although I don’t think the rib structure is particularly complex. I have already played with the mesh settings, checked if the closed brep has errors, I have used rebuild mesh from Pufferfish and I am slowly running out of ideas.
I’m actually sure that the whole thing used to work until my computer crashed. I also deleted the Brep to Mesh component once today and added it again, then it worked briefly…

Maybe you have some suggestions for me.

Many thanks Tim

  1. Don’t use a Ruled Surface…

  1. Your extrusion vertically upwards creates a self intersection

What else? Loft works even worse

Give me a few minutes.

Wow thanks! A completely different approach.

nice!
…one more aproach: thought it might help to avoid curves, surfaces…
