Adjust points rotation based on underlying lines layer

Jake-MacLean — Mon, 07 Jul 2025 16:42:42 GMT

Hi all,

I am trying to figure out a way to adjust the rotation of point symbols based on the orientation of underlaying line features. It is a utilities map and so I have features such as end caps and valves that I am trying to align with the water/sewer mains they are connected to. But so far have not been able to figure out how to essentially extract the orientation of the closest line and use it as a value to rotate the symbols.

Can anyone help with this/has anyone needed to do something similar?

Thanks

You could use an Arcade expression that you can use with Attribute Rules on your dataset that will accomplish this. There are some great example Arcade expressions that you can use to implement this here:

Hi @LeonS ,

with a little bit of tweaking I got this to work great.

I made two versions, one to calculation rotation for inline features, and another for perpendicular features.

Really appreciate it!

Thanks
