This is still extant. I'm not sure if this can be solved without introducing the "multi-events" (see #16 )

Many thanks for the reports and the example files, by the way!

We are trying to solve that through postprocessing of the skeleton in our port of the library: https://github.com/prochitecture/bpypolyskel/issues/5#issuecomment-706172626

Wow, that picture of those buildings is pretty awesome, I love it!

I'll link to your port in the Readme :)

As for the erroneous edge in the T-shaped polygon: I don't actually think it's an extra edge, I'm pretty sure it should be there, except it should be horizontal. I understand this isn't ideal for your application, but it must be there, otherwise it wouldn't be a tree. Yeah, it can be eliminated in postprocessing, I guess, though the underlying problem bothers me anyhow.

That would be nice. Here is the description of our port:

A port of Botffy/polyskel library for Blender that outputs polygons formed by a straight skeleton. 'pip install mathutils' to use it as a general purpose library independent of Blender.
