Thread: Expression for Angle of Deflection in Label?

    Default Expression for Angle of Deflection in Label?

    I'm trying to create an expression to calc angle of deflection on an alignment.
    I've never written a expression before so I'm not sure where I'm going wrong, but at this point I've frustrated myself to the point that I can't even logically work through.
    I tried the formula ATAN2({PI Northing},{PI Easting}) and formatted the result as angle.
    Has anyone had any luck with this?
    My apologies if this is an overly simple question, I think I've worked myself into a stupor over this.
    Thanks in advance

    Try this:

    Select the alignment, select Add Labels in the ribbon to open its menu, select Multiple Point of Intersection. This will label all the PIs of the selected alignment with a Point of Intersection label. This label entity has Delta Angle available as a property for labeling.
