Hidden Line rendering is not displaying correctly in front or back views. Other views are correct. Attached are some samples and a VW file. Sample 1 shows what a front view, hidden line rendering should look like. I had to cant the model a small fraction to get it to render correctly. Sample 2 is a Front view, hidden line rendering and is showing lines that should be hidden, especially in the bottom center of the model. Sample 3 is an isometric view of the model. Any help is appreciated.
