With AutoCAD Map 3D toolset, you can backup and exchange your user-defined coordinate system dictionary definitions. To do this, export the definitions to an XML file and share the XML file with your partners.
Coordinate system dictionary definitions include coordinate systems, datums, ellipsoids, geodetic transformations, and geodetic transformation paths.
Different type definitions might be identified by the same code, for example, WGS84 is a code name for a datum and an ellipsoid.
Limitations for this command include duplicate entered definitions will be ignored and that exporting the property “category” is not supported.
You can also load a LSP file to complete the export.
(command "MAPCSLIBRARYEXPORT" "CA83IIIF" "C" "WGS84" "D" "WGS84" "E" " " "Y" "C:\\CSLibrary.xml")
