Helical sweep along variable trajectory

It is not clear in your post what your expectations are with regards to the design intent for this feature. The variable option you are referencing enables the sketch to change as it is swept along the trajectory path. If the variable option is not working, then that is most likely a result of your sketch not being constructed in a way that supports this functionality. Your post shows some sketch constraints that are likely preventing the section from being variable (the symmetry constraints are most likely the issue). Try deleting the symmetry constraints in the sketch and then the 60 deg included angle could be variable within the helical sweep. I am assuming that it is the 60 deg that you want to vary, if not you need to provide more clarity on your design intent.

Hello,

Thanks for you feedback!

My design intent actually is to have the helical sweep to be conical following the surface in the section below and not remaining parallel to the centerline.

I want the triangles to be aligned with the red lines.

I tried removing the symmetry constraints and angle from the sketch, but still doesn’t work.

Thanks
