Connecting pipe by MEPover Package with tiny angle

Revit
#1

I’m working on a tunnel project and trying to generate the water deluge pipe along the control line. The thing is I generated all the pipes successfully but failed to connect them with the node MEPFitting.ByMEPCurves

I believe the problem is the angle between these 2 pipes is too tiny, but isn’t it very normal in a linear MEP design? Is there anyone have a idea about this? Thank you so much!

Hey, can´t help but I got same issues using MEPFitting.ByMEPCurves with cabletrays. I think it is a general problem with Revit. I tried to adjust the possible bending-radius in the used fitting-families, but got the some issues. I´m looking forward for possible solutions .
