How can I wrap a sketch to a spiral face?

Hi,

 

Wen I try to wrap the sketch to a face, which follows spiral curve projected from a helix, I get an alert message. As the picture indicates, the projection (wrap) is not complete. Can someone explain why this is happening, please?

 

And to the experts: Is there another way to achieve a result?

 

FYI: I am using NX10 and have a lot of parameters to produce variants in the end.

The issue is probably caued by the location of the plane.

 

If you move the plane to be tangent to the surface near the middle of the spiral, do you get a better result?

I would suspect that the issue is that the Wrap function does not support going more than 360 degrees 'around' a model.

 

AS for an alternative approach, you might be able to 'flatten' the spiral surface, draw the curves on the flattened model and then map them back to the original face.

Make a solid of the sketch and then try global shaping.

Flatten and forming is in NX11

Hello,

 

I want to thank you all. 

Unfortunatelly, I had to reconstruct the whole problem and forgo the sketch wrapping along. However, when I have more free time I'll try the suggestions posted here. 

 

many thanks
