Boolean ExternalDataFile.IsMainFile { get; set; }

Gets or sets the main file flag of the external data file. The nodal coordinate data for the selected main file is processed by the mapping utility. The nodal coordinate data will be skipped in all other files. Only one file can be set as the main file, otherwise, an exception will be thrown during the import. If the import format is MAPDL, the value of this property will be ignored as the MAPDL CDB file will always be treated as main file during the import.
