sweep protrusion doesn't work with datum curve in pro/engineer.
it only works when trajectory lies on single plane or only 3 points are used to make datum curve.(3 points always lie on a plane)
is it a bug or some system constrain. any other work around for this.

Make datum curve through datum points lying in any plane...
i think you have used that...
Now, whenever you have a trajectory passing from different planes, use variable section sweep command to create x-section.
You need redefine the sketch in order to adjust in the critical loops of the curve
in order it to work , u should have datum curve or sketch , not a sandwich of both datum curve & sketch
Try using swept blend with a 3-d datum curve. I have an example in my uploaded files..
