I met a problem, that is on the same plane there are two or more TriMesh objects (2D polygons), one is bigger than the others and the smaller ones are totally inside the bigger one, but the shapes of them could be random.
I see what you are going for, but there is nothing like that in our API and not likely to be anything like that in the near future. If you write a tool like that yourself, we encourage you to post it for others to enjoy.
I will work on that later then and if I got it solved I will share that with the people here.
Thanks anyway!
