Field Calculate Annotation Angle

Jwalke20 — Thu, 29 May 2025 21:33:07 GMT

Attempting to use the field calculator to change the Angle field in a a feature linked annotation class that resides in a file geodatabase. Specifically, I am adding a value to the current value. Error 999999 is thrown.

def calcAngle(old, value):
newAngle = old + float(value)
return newAngle

You need your Expression and its properly format etc

see more examples including code blocks

Calculate Field Python examples—ArcGIS Pro | Documentation

# Expression calcAngle(!Angle!, value=5.0) # field name in ! ! and value=5 # Code block def calcAngle(old, value): newAngle = old + float(value) # although float shouldn't be needed return newAngle
