I'm trying to sweep a circlular profile along a spline that begins with a helix and ends in a hook-like structure.  When  I do the sweep, the profile doesn't follow the path for a portion of the sweep.  The Property Manager options I have are correct as far as I can tell based on their descriptions in the help files (see them in the picture attached).  The sweep feature is in [Part4^TestAssy]...

Anyone have any idea why this is occurring and what I can do to fix it?

Thanks!
