Hello,

I am trying to sweep a sketch along a helix to form a sort of rib along the length of a cylinder, similar to an auger. The cylinder has a taper at one end, and I need the resulting rib to follow the taper. I have tried using a variable rate helix and changing the diameter at short intervals, but once I try to sweep the profile down the helix, it starts floating after it gets to the taper. Does anyone know of a feature where I can get the sketched profile to follow the surface?

thanks,

Jesse
