Having issues with the lofted base command.  I'm designing a part that has two halves that are mirror images of each other and doing a lofted base from a rectangular face to a circle with a guide curve.  When I do the command for one of the parts it does the loft as expected with a straight curve between the surfaces.  However, when I do the command on the mirror part it twists the loft and I cannot get it to loft straight like the other part. The face, circle and guide curve are identical in the two parts, but one twists and the other doesn't.
