The File > Import > Grids command imports a coordinate system into the model. This command recognizes XML and XLS files that have been exported from a different model. The software prompts you to change duplicate coordinate system names before importing.
You can modify the distance and angles in the exported XML or XLS in any accepted Units of Measure format and then import. It is easier to modify the inputs in XLS than in XML. Refer to the AvailableUnitFormats sheet in the exported XLS file to understand the accepted Units of Measure formats.
Grids exported to XLS from versions 2014 or older will import successfully into versions 2014 R1 and newer; however, no grid lines will display. You must modify the grid lines and define the associated planes for the grid lines to display. We recommend you manually edit these older version XLS files (those exported by version 2014 or earlier) to include the AssociatePlanes column that is present in the newer XLS versions. Export grids to XLS from your current version and use that file as an example for editing your old version XLS files.
