Curve on Srf encounters problem with Lofted Srf

Hi, I was trying to interpolate three curves from three groups of three points each on a surface. It worked fine for the first two curves, but the third curve rotated in the wrong direction. The surf is generated from lofting three circles. I suspect the third curve is trying to avoid the seam on the lofted surface. Is there a way to get around this?

mh, now I understand your Problem. I would create one curve and rotate it around the axis of the Surface. As it is a revolution it works fine.

but the surface created by revolving also has a seam...

 I mean you take the first ( working) Curve and rotate this one tow times around the axis. The lofted surface is fine.
