The present invention provides a method, system and computer program product for routing multiple paths through polygonal obstacles. In a preferred embodiment, the method begins by offsetting the initial paths through the obstacles from the obstacles to form adjusted paths. If it is determined that any adjusted path encounters a new intersection, the adjusted path or paths are modified to form revised paths. The vertices of each obstacle are labeled. All the revised and all the adjusted paths are sorted. Then, according to their sorted order, the revised and the adjusted paths are reconstructed to form offset paths.
