To Install the ArcGIS Projection Engine Data

It is recommended to install the ArcGIS Projection Engine Data before bringing ArcGIS data into your drawing with the Autodesk Connector for ArcGIS. The Projection Engine Data prevents a coordinate offset due to any datum transformation occurring when you bring ArcGIS data into a drawing. This offset due to datum transformation may occur when using coordinate systems that do not have an EPSG code or if any data transformation occurs between coordinate systems.

Tip: To prevent a coordinate offset issue from occurring when you save back to ArcGIS, use a coordinate system that has an EPSG code.
Note: The ArcGIS Projection Engine Data only needs to be installed on your local system once. If you have previously installed the ArcGIS Projection Engine Data to use the Autodesk Connector for ArcGIS with Autodesk Civil 3D, you do not need to reinstall.

  1. Close InfraWorks.

  2. Go to https://developers.arcgis.com/downloads.

  3. In the ArcGIS Maps SDKs section, click ArcGIS Maps SDK for Qt.

  4. In the Projection Engine Data section, download the latest version compatible with your version of InfraWorks.

  5. Unzip the downloaded file to a local folder such as C:\Users\ <username> \Downloads. By default additional subfolders are added to the folder name when the content is unzipped. For example, C:\Users<username>\Downloads\ArcGIS_Runtime_Projection_Engine_Data_200_2_0\pedata.

  6. Click the Windows Start button to display the Search Programs and Files box.

  7. Enter regedit and press Enter to open the Registry Editor.

  8. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\InfraWorks\ArcGIS.

  9. Double-click the registry item ArcGISProjectionDir to open it.

    Note: If this registry item does not exist, create a new String Value in that location named ArcGISProjectionDir.

  10. For the Value Data, enter the folder that contains the unzipped files, for example, C:\Users<username>\Downloads\ArcGIS_Runtime_Projection_Engine_Data_200_2_0\pedata.

  11. Click OK.

    Note: To prevent a coordinate offset issue from occurring when you save back to ArcGIS, use a coordinate system that has an EPSG code.
    Note: Some coordinate systems are not supported when publishing to ArcGIS or exporting to FGDB. If a model is assigned an unsupported coordinate system, publishing to ArcGIS or exporting to FGDB will not proceed.

    In addition, there are three categories of coordinate systems which are not supported:

    • Obsolete Coordinate Systems
    • Arbitrary X-Y Coordinate Systems
    • Test Only Coordinate Systems
