I’ll describe my issue in following way.
I want to paint a surface / shape, the shape is rather exotic has a lot of turns and bends and parts sticking out.
I have this surfaced defined in grasshopper. I know the width of my paint brush.
How can I define the shortest travel/painting distance with my brush such that I can paint the entire shape.
In the end it would be the idea to have a set of polylines (with the shortest combined length), that if these are sweeped with the correct width, would cover the entire shape.
Painting outside of the lines would be allowed and is not an issue (we’ll tape off the the surroundings )
Taking your paint brush of the surface to relocate would also be allowed (but preferably this ‘travel distance’ is counted somehow)
