I’m not even sure I understand my problem.
My goal is to take an arbitrary closed curve, create two different offsets at different distances, and join parts of each offset into a closed exterior curve based on angles from the center. Like this:
In that example I have an interior ellipse, and two outside offsets that are trimmed at two angles, and then linked with a line.
In grasshopper, I’ve gotten as far as identifying the intersection points:
…but I’m stuck on trimming the curves. Worse, I’m second guessing whether this is even the right approach to the problem.
Should I be doing something like dividing the curve into 720 segments and offsetting the points by different amounts depending on whether they’re inside or outside the dividing angle? Is there a more elegant way?
