Hi Joerg, set the option for Twist = Flat in the Sweep options:
Then additionally push the "Set flat direction" button that appears in the options once Twist=flat is set, and pick 2 points along the y axis to tell it the direction:
When twist = flat is set, the profile will only rotate around the given axis direction. The default axis is the world z axis, since your helix is aligned to the y axis instead that's why you need to use "Set flat direction" as well.
