Division by zero error

[mole99]

Hello, thank you very much for your script!

Unfortunately, I found a division by zero error when I run it on one of my layouts.
The division happens in this line and the one below: https://github.com/mbalestrini/GDS2glTF/blob/43b444e69b9b1e9e117560c48eac45d5437bdf15/gds2gltf.py#L234C1-L234C66

This is the troublesome GDS file: https://github.com/mole99/tt08-aicd-playground/blob/main/gds/tt_um_tt08_aicd_playground.gds

I would appreciate any help, thanks!

I could track down the error to the manual routing part of the design:

It seems this issue is much more general: Any path that is drawn leads to this error.

For example this simple path:

Leads to the same division by zero error.

GDS is here: path.zip
