I try to solve this simple problem for nearly a month and cannot find easy solution.
Im trying to extract all the shapes created by intersecting all the lines from any group of curves, create new shapes (eventually do a contour - also fails) and make them separate polygons.
In yellow, what i get,
In cyan/green what i want (for every red line intersection).
I cant use the intersection tools as they are slow and i need at least 3 of them which creates a real mess. I tried other variations but none seem to work
Essentially create a surface larger than your shape, split that surface with your rectangles, and get rid of the inner and outer surfaces you don’t want by removing the two largest area surfaces.
I’ve found that the Geometric Region of Heteroptera doesn’t always give good results when curves are involved, but works well for lines, as in this case. Otherwise, I’d use Split Surface as you did.
