ArcMap has a tool that is really useful for measuring angles in the COGO Report tool. Perhaps ArcGIS Pro could bring this in.


The Measure tool has an option to Measure Angle.  Will this work?




We have tried that option. The angle from using the measure tool doesn't seem to match the angle we need to rotate features. For example, when using the angle option in the measure tool, we would get something like 64 degrees, but when using the rotate tool, the angle is 19.42101239. We need to have the angles in Arthimetic and not Geographic to match data we import from CAD files. Not sure if this is what is happening or not.

After internal discussion with others on Esri staff ( @Scott_Harris   @JenniferCadkin ) we may need some more information. However, based on what you’ve indicated so far we think that you are using the “Vary symbology by attribute” property to rotate point symbols. Is that correct?

Going with this, we put together a mini test workflow to rotate an Arrow point symbol to be oriented along the same direction as existing features. This should help to show the relationship between the measure tool’s direction units and values, and the point symbol's Rotation style.

The test workflow is as follows:

  • Create a double field on a points feature class and call it “Direction”
  • Add the point feature class to the map
  • On the point layer, set the properties on the point symbol to be an arrow.
  • Rotate the symbol so that it is pointing north in its default state. Do this under Properties -> Rotation, set the angle to 90°:


  • Using the Vary symbology by attribute, set the Field to Direction, and set the Rotation style to Arithmetic:


  • In the project backstage go to Options -> Units > Direction Units and set the default direction to Polar. Also, click the cell in the number column to get the Direction Formatting, and change the direction base unit to Decimal Degrees, and set decimal places:


  • Add point features near or on the segments that will be measured.
  • Use the Measure Direction Distance tool and snap to and click the first point on the segment, then snap to and double-click the second point.
  • Select and copy the Direction component from the measure tool dialog
  • Select the point and open the attributes pane, and paste the direction into the Direction field.
  • The arrow points in the same direction as the measured line:
