Sheet Metal Issues

[cwilliamrose]

At first I thought the problem might be the offset spline used for the inner edge so I changed it to an ellipse. That didn't help, it still would not create an edge flange on the inside. I then made the base part as one half, intending to mirror it after forming the flange but it would not let me mirror the part. It did however form the half inner flange. I added the other half of the base using another extrusion and flanged the inside of that edge. Worked fine. The outer edge took the edge flange with no issues so the part is complete,,,, except the flat pattern shows an error because of the inner flange. Notice in the image below the the two halves of the inner flange are not tangent for some reason.

So, I was able to do it but the sheet metal part is not happy. Not sure why. I'm also not sure why there's a 97K file size limit on ZIP files -- I can't upload my revised file for you to look at............Bill
