List of points of intersection of polygons area

[qualitysof]

Hello everyone, I'm looking for a routine that allows me to find the list of points of intersection area between 2 or more polygons according to figure I show the link.

 

I hope someone can help me.

 

Thank you.

Sorry no one answered previously but its simple use Bpoly then pline co-ords Lisp then Erase last only hiccup is you have to pick the approx center point. Search here so many examples of pline co-ords.
