Hi Michael,

This is more what I was thinking - if you select a large group of lines and try an offset to all MOI struggles with the output. You can see from the illustrator output that the offset is clean. What I mean from variable is able to change the width of the line. With this clean output it can be converted to a 3d object from which a lean nurbs model or mesh created. (Manual method to the grasshopper exoskeleton workflow)

Like the Voronoi generator another favourite of mine is the Taprats generator.

Its vector EPS outputs are of very high quality and great for creating repeat patterns.
