Include the Scale Factor column in a point file format that is used for exporting points.
Use the Scale Factor column name to define a point file format column containing a calculated convergence angle. Scale factor is the value used to reduce or increase a local (geodetic) distance so that it equals the grid distance.
Use this column only when you export point data. To export points using a format containing a scale factor, you must have set a zone in the file format and drawing, and you must turn on the transformation settings for the drawing.
Export the scale factor by using the method specified in the transformation settings, such as Prismoidal or Unity.
