Simplify Face

So I have this mesh and I want to simplify delete/simplify the line in the midlle of each surf to unroll later to create a developped volume for my architectural model

Is there anyone here that can help me to simplify this ? Any algorithm or plugin or command ??

Hi Philippe -

The object in your picture doesn’t look like a mesh but the output of ToNurbs on a mesh.

I’m not sure if you are referring to the isocurves of a surface or the edges of the surfaces. I assume the latter. You can run the MergeAllCoplanarFaces command to create single surfaces from coplanar surfaces. As meshes often are rather messy, that command might, or might not, help in this case. It’s always a lot more useful to get help if you also provide the 3dm file.
