To Import and Export User-Defined Property Values for Points
If you have a point file that contains custom properties, or you want to export custom point properties, you can set up a point file format and then use it with the Import and Export commands. You can add your custom properties, called user-defined properties, to the point file format. As prerequisites, you must first define a user-defined property classification and the user-defined properties that are contained in it.
When you compose a Point File Format, the user-defined property names are displayed in the Point File Formats - Select Column dialog box. You can select a property and assign it to a specific column.
