I am looking for a way to automate a specific kind of iso line extraction. Please see attached screenshot and Rhino file. These are unrolled skins for a curved/rolled/bumped shape that require accurate marking of the iso lines for alignment purposes. I have been doing this manually for far too long and now have a large project with over 50 unique shapes similar to this. The basic requirement is that I need the staggered line length along both edges of my surf, which get laser etched when cutting the parts. This lets my brake press operators know how to align the part when bumping. The stagger is super helpful as it prevents catching the wrong lines. At this density it is too easy for eyes to blur and misalign.
Ideally a script or gh that would extract iso curves every x amount and then trim every other one as shown.
But at this point I would love just a script to automate extracting iso curves every x amount. Then I could trim accordingly.
If anyone has anything already or any suggestion other than teaching myself grasshopper I’m all ears!
