Hi,

I am trying to create a pattern to miter an ellipse shaped tube. Using the ellipse sketch tool as the base for the tube doesn't seem to be compatible with a sheet metal unfold feature. Using 2 small circles and 2 large tangent circle to make the ellipse works but the resulting unfolded tube is not correct, the fish mouth is not completely unfolded.

Does anyone knows what happens here and how to solve this?

Thanks
