How to set pipe slope using MEPover?

[dylim]

Hi there,

I am trying to make pipe along the proposed line.
So i found MEPover and in revit 2019 it was working properly.

But when i tried it in Revit 2020, all pipes created from MEPover pipes.byline have no slope.

I checked Python Code it gives start point and end point as pipe create parameter.

Please let me have a solutuion

thanks!

sorry guys i made silly question.

I shouldve give P2.Z but I gave P1.Z as end point.
