Hi Markus,

there is a 2D Minkowski sum for polygons consisting
of linear and circular arcs in the making, but it is
not ready yet, and we don't want to make a commitment
for a release date.

Best regards,

Andreas

Hello,

I'm new to CGAL and found information about to create a offset of a
Polygon_2 with create_exterior_skeleton_and_offset_polygons_2. That works
fine but I need a offset from the combination of Polygon_2 with
Circular_arc_2. If You suppose to use Arrangement_2 with planar curves, is
there a offset function and how to convert back to polygons and circular
arcs.

Thanks for Your help,
Markus
