Annotate Pipe Slope Direction

Hello Community

I am trying to build a script that annotates slope pipe direction.
Below file .rfa is the Detail Items for Arrow Direction.

Direction Arrow.rfa (320 KB)

Below file .dyn is Dynamo Script which I tried to create the pipe slope direction

Pipe Slope Direction1.4.dyn (94.5 KB)

I tried to recreate the pipe as a line with reference to their slope direction which I failed

Problem: I need to get the arrows according to the pipe slope. But it fails in few cases?

Output Required: All pipes in the view need to annotate according to their slope direction

Hello @Mepdot,

I have used arrow family to show the direction of the sloop.
