hello,
I am developing a CAD application.
From a set of 2D points, I would like to get the outer edge of a building
floor.

I have used the alpha shape algorithm and he successfully gave me a
std::vector<Segment_2>.
When I draw the set of segments, I have a polygon with several holes.

Now I would like to keep only the outer Polygon and discard holes polygons

Is there any CGAL way to achieve this ?
Thank you very much
