Modelling Problems-wrapping profile with helix

[APE Design Ctr]

Interesting scenario. I need to create an auger bit, where the ribbon of the auger wraps around the shaft.

I have created a helix spiral, and a profile of the ribbon needs to wrap around this path to create the auger. When extruded, the profile seems to turn at a different axis rather than following the path.

I could send a rendering to show the issue.

Let me know if you can help.

Thanks

What do you mean by 'profile of ribbon'? Where is the center of the ribbon profile located. Extrude along Path uses the coordinates of the center of the profile to track the path.

I am using a rectangular profile to mimic the piece of steel that wraps not unsimilar to a ribbon around the shaft. Can I email you an image?

Thanks

I think you will get a much more predictable result by using the sweep comand with a pitch value. You can sweep the entire spiral by setting the sweep value higher than 360?.
