Smart offsetting of curves with trimmed intersections

I’m trying to offset a network of curves in order to create planar merged offset. Another idea can be of a single line plan, then converted to offsetted walls with those single lines being the central spine of the offset walls. The offsetting must be done in such a way that the intersections must be trimmed off.

How can I do it both for a scenario when those intersecting curves are

1 . on one single plane?

  1. On a curved surface?

For coplanar objects, the easiest method I know of is to make planar surfaces from each of the offset pairs then BooleanUnion the surfaces together and finally MergeAllFaces.

I do not however know how to do that in curved space…

Why not using Clipper ? Classical answer when speaking about offset…

Clipper is working when the surface is planar. Thanks a lot for this plugin.

Now if I want to convert the offset network to a surface like pathways, how should I do it? Region difference crashes Rhino after hanging it.

What is the way to use clipper so that the offsetting trims work on curved surface as well? I am getting the following result.

The original cellular grid was generated by using paneling tools. I am attaching both my model and grasshopper file.
