Hi group, Does anyone know of a facility for Polygons (graphics) with holes inside? I guess there is no such thing as an oriented polygon in Mathematica? Or a polygon consisting of disjoint lines (inner and outer contours, clockwise and counterclockwise)? I can see that it is possible to connect outer and inner contours using a dummy line, but that is not so easy to program in a generic way. Solutions such as creating an artificial hole by another Polygon in the background colour are not really acceptable. Polygon's with holes would be very useful for maps etc. Sincerely HK
