Importing an ArcMap document
Import this map document if you previously used ArcMap and would like to transition your existing Map Exchange Documents (*.mxd) to access in ArcGIS Pro.
Note: You do not need to perform this step if you've never
used the HxGN EAM GIS toolbar (you are implementing the ArcGIS Pro add-in for the first time) and do not have existing *.mxd
files.
