Certain areas of my drawing contain elements with coincident edges, and when I cache that drawing I don't always get the specific edges I want to see. Therefore the line styles may change from edge to edge.
Because hidden line processes such as Cached Visible Edges have no way to know which edges are "preferred" when multiple elements have coincident edges, some may take priority over others and the desired results may not be achieved. As a workaround:
This process should allow both set of lines to be created in full with only the desired lines displaying at any given location.
