I tried the following using Attribute Assistant (All methods - Attribute Assistant | ArcGIS Solutions😞

1) Using the Custom Valve Symbols I created per what I mention at the start of this post.

2) I used ANGLE method to obtain a Geographic and Arithmetic Angle for each pipe.

3) Using the INTERSECTING FEATURE method, I transferred the Geographic Angle and Arithmetic Angle to respective fields in the Valves Feature Class.

4) The results were the same.

CONCLUSIONS:

- If you use custom valve symbols as I illustrated in this post, they will not rotate to orient with the pipelines. You must go through each one and manually rotate them one at a time.

- The JUNCTION ROTATE method does not rotate custom valve symbols to orient with the line.

- However, if you use the ESRI AMFM Water Valve Symbol, circled in red below, the valves will rotate correctly (But, you must use the JUNCTION_ROTATE method to be successful).

- I would not use custom valve symbols unless you want to rotate each one by one. Very tedious if you have hundreds of valves.

- Attribute Assistant is AWESOME! very useful despite the problem I found here, which has nothing to do with the Attribute Assistant.

I have an idea that might work, if I use Attribute Assistant to:

1) calculate the Geographic Angle of the Pipe Lines

2) then do a Spatial Join of the Lines with the Points (Valves)

3) then do Field Calculate on the Symbol_Rotation field in the Valves Feature Class in order to add the value in the Angle field to the Symbol_Rotation field

Has anyone tried this? I wonder if it would give the same results as I illustrated at the start of this thread?
