Overlapping parts on the output result.

[misan]

Hi,

I am testing nest2D (ubuntu 20.04, Python 3.10.6). The sample example works as expected, but I have tested with other, more complex shapes, and I am getting parts overlapping on the output. Do you know how to fix that?

I am including the result I got.

Trying the same parts (file below) with SVGnest it does work ok.

Here you have SVGnest output ...

Hi, I came across the same problem. Be aware of the limitations of the https://github.com/tamasmeszaros/libnest2d lib that is being used:

"At this stage it works well for rectangles and convex closed polygons without considering holes and concavities."

This could possibly help you https://github.com/tamasmeszaros/libnest2d/issues/49

Thanks a lot, @PhilippBau; I will try the solution you linked. However, some of my parts have concave sections and that could well be the cause of it.

Cheers!

@misan If this doesn't work with concave polygons I can recommend this repo:
