Pipe fails

Hello everyone,

I’m having an issue, don’t really know why pipe fails. (pipe outputs empty parameter)
It works fine with any other curve but not this one.
What could it be?

Many thanks!

It is not a good curve, you shouldn’t make a spiral with a super dense polyline. Pipes usually break at polyline control points to result in segments. In this case I suspect there is just too many short segments, so too many angles. Just fit it to a degree 3 curve.

Thank you very much!!

Works perfect now!
