I've been working with a nose cone which was 3d scanned and pulled into solidworks as a surface. To make a solid I set up planes at every inch of the nose cone and used intersection curves to get sketches at each location. Now I have been trying to loft between each of these sections. The loft works perfectly until about the last two sections where it begins to rotate and twist forming a vortex like deformation. I was unable to form guide curves to help solv this and the conectors do not seem to do much when dragged around.

Any tips or solutions for this problem?

thanks!
