Include the Convergence column in a point file format that is used for exporting points.
Use the Convergence column name to define a point file format column containing a calculated convergence angle. In state plane coordinate systems, the convergence angle is the difference between a geodetic azimuth and the projection of that azimuth onto a grid (grid azimuth) of a given point.
Use this column only when you export point data. To export points using a format containing a convergence angle, you must have set a zone in the file format and drawing, and you must turn on transformation settings for the drawing.
