Here’s an object which opened the POE door for me, it is originally made by GS, I have only issued the offset-lines script.
As you know it is hard to understand how POE works.
Basicly you define the polygons, add information of contours and edges. Then you open the add on and perform operations. What you get is almost similar data as you put in. Of course it must be processed to get resulting polygons.
I think there was a bug in the script so that it works not in all situations, but maybe this helps a little.
