Abstract:
1. A method, comprising: creating a drawing to define at least a first path and a second path, wherein the first path and the second path overlap, and wherein the first path has a first path attribute, and the second path has a second path attribute; determining a first overlapping region wherein the first path and the second path overlap; deriving, by a processor, an apparent stacking order for the first overlapping region, wherein the apparent stacking order is determined at least in part by: editing the drawing by modifying at least one of the first path and the second path, and at least the first overlapping region is modified and a second overlapping region is created; assigning the path attribute to at least one of the first overlapping region and the second overlapping region based on the derived apparent stacking order of the first path and the second path; and displaying the edited drawing of the first path and the second path on a display.
