Anyone have a code snippet I can use to accomplish this?
I'm currently answering a similar question here:

Calculate Geometry Attributes can calculate Line Bearing, if that's what you need.

This is what I ended up going with. Thanks!
// get a list of line parts var paths = Geometry($feature).paths // for each part, loop through each segment and get its angle (arithmetic angle -> East=0°, North=90°) var angles = [] for(var p in paths) { var count_p = Count(paths[p]) for(var q = 1; q < count_p; q ++) { var a = Angle(paths[p][q], paths[p][q-1]) Push(angles, a) } } // get the mean arithmetic angle var arith_angle = Mean(angles) // rotate so that North = 0° var north_arith_angle = arith_angle - 180 return north_arith_angle + IIF(north_arith_angle < 0, 180, 0)
