Add sweep for a pipe bend with Creo DME 4 produces funny shape

[ptc-6007232]

Hi,

i'm trying to create a non 90deg pipe bend in Creo DME 4.0 and I keep getting an odd output:

Anyone know why this is and how to properly create a bend?

Thanks!

It looks like the radius in the sweep contour is smaller then the section dimension.
If you put the sweep contour on the outer side of the section (in the picture on the right side) it will work.

It is because the cross section at start is not perpendicular to the spline geometry.
