Amir,

Yes - for a given side of the polygon, I need a full gable. I would then use this capability to mix gable and hip across a single roof geometry.

If you have some code, that would be great!

Thanks very much!

Do you want a full gable? (that means, that an entire side is vertical, and not
only part of it). You can compute a weighted straight skeleton in which the
gable has a very small speed, but CGAL does not support weighted straight
skeletons. I can send you some code for it, if you like.
