How to create a helical sweep with a circular face on a section not normal to the trajectory?

There is a circular face and I want to create a helical sweep (like a spring) from it. However, the origin circular face is angled such that it is not normal to the helical trajectory.  Currently using Creo Parametric version 8.

I may not be understanding the design intent of the swept geometry. Could you clarify the comment above about a rotating projection?

 

I only have Creo 7 or Creo 9 installed. I swept the section of the face using the normal to projection option (using DTM Top as the reference) which may not be accurate. I have enclosed a neutral file here which you can open in Creo 8.

You could use volumetric helical sweep where you can model the cutting tool with incline tilt angle.

Thank Michael for the replay. However, with volumetric helical sweep, the cutting tool axis can be only titled around one axis, either X-axis or Z-axis. My surface normal could be arbitrarily oriented.  Any further suggestions?

To make curves that maintain tangency for things like springs with extensions and the like, I have used equation driven curves and graphs.

If there was an illustration of what you are attempting it would be easier to make more specific suggestions.

Please see attached zipped prt file. I simply want to protrude the circular face along the helical curve. Thanks.

Does this appear to represent the desired geometry?
