To Define an Automatic UDF on a Coordinate System
1. Click Framework > Automatic UDFs. The Automatic UDFs dialog box opens.
2. Click to select an automatic UDF from the library and define it on a coordinate system, or click to define another instance of the currently selected automatic UDF on a coordinate system.
3. Select a coordinate system on which to apply the automatic UDF definition.
4. In the variable dimension list, type values for each dimension or select a dimension or a parameter from the list. All named dimensions and real and integer parameters in the model to which the selected coordinate system belongs are displayed. If you select a dimension or parameter instead of typing a value, the value of the selected dimension or parameter is used as the dimension value for the UDF.
5. After defining all variable dimensions, click to apply the definition.
