Hi Brian, probably you had the default Twist:Freeform active for the sweep. That will generally spin the triangle more than you want for this kind of controlled sweep. So setting the Twist:Flat option will solve that, it will only pivot around the world z axis when that is enabled. Make sure your helix runs up and down vertically along the z axis to make that work right.
