You can use the Autodesk® Civil Engineering Data Translator 2015 extension to translate AutoCAD® Civil 3D® files to files that can be used in Bentley® GEOPAK® and Bentley® InRoads®, and to translate GEOPAK and InRoads files to files that can be used in AutoCAD Civil 3D.
The commands for the Autodesk Civil Engineering Data Translator are available in the AutoCAD Civil 3D Toolbox.
The Autodesk Civil Engineering Data Translator requires an Autodesk® 360 account and an Internet connection. If you do not have an Autodesk 360 account, you can create one when the Autodesk 360 log in dialog box is displayed when you run a translation command, or you can go to www.autodesk.com/launch-a360 to create an account.
After running a translation command, you can use the Job Monitor dialog box to monitor the progress of the translation and to download the files when the translation process is complete. A report file with an .xlsx file extension is created for each translation job. The report file lists what was converted and lists any differences between the source objects and the converted objects.
