I am trying to sweep a sketch around a guide that is circular, but has a "bump" in it. The bump is a segment of a larger circle concentric with the first that has two tangent curves attaching it to the smaller circle. When I select these curves as the guide NX give me some convoluted pretzel shape as the result.

No mad. I wish I could, its military though. Maybe I can creat something similar and show a picture

Sorry, no picture - no help.

That being said, try creating an offset curve of your original path and use this as a second guide curve.

Are your section curves positioned at the end of one of the guide curves? If not, you will get a pretzel shape. See attached examples.

Thank you mmauldin! The bump was at an odd angle so my section curve had just been in the middle of the cirlce. What you said to do worked!

John, I wonder if offsetting a second guide curve will produce the same result as what mmauldin said even if the secion is not at the end of one of the guiding curves? I will have to test this
