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 whole circle bearing and the projection of that whole circle bearing onto a grid (grid whole circle bearing) 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.
