To Translate Bentley GEOPAK and Bentley InRoads Files to Files that Can Be Used in Autodesk Civil 3D

You can use the Autodesk® Civil Engineering Data Translator to translate Bentley® GEOPAK® and Bentley® InRoads® files to file formats that can be used in Autodesk® Civil 3D®.

1. On the Windows® Start menu, click Autodesk Autodesk Civil Engineering Data Translator Civil Engineering Data Translator.
2. In the Civil Engineering Data Translator Client Login dialog box, enter your email address and click Next.
3. Enter your password and click Sign In.
4. In the Civil Engineering Data Translator Client dialog box, click the browse button .
5. In the Open dialog box, select the file to translate and click Open.

   You can select the following types of Bentley GEOPAK and Bentley InRoads files:

   • Bentley GEOPAK Project Data: TIN and GPK files.
     Note: For GPK files to be translated successfully, they must be named job***.gpk, where *** can be numbers or letters (for example, job001.gpk or jobabc.gpk). The "j" in "job" or any other letters used in the file name can be lower case or capitalized. The file name cannot include special characters such as #.
     Note: Upload each file separately. You can use data shortcuts to link the data in the resulting drawings together.
   • Bentley InRoads Project Data: DTM and ALG files.
     Note: Upload each file separately. You can use data shortcuts to link the data in the resulting drawings together.
   Note: For information about how to translate DWG files to files that can be used in Bentley GEOPAK and Bentley InRoads, see To Translate Autodesk Civil 3D Files to Files that Can Be Used in Bentley GEOPAK and Bentley InRoads.
6. Depending on the type of file you select, different options are displayed in the dialog box for you to specify:
   • If you selected a GPK file, enter the unit type of the source file.
   • If you selected a TIN or DTM file, specify the Surface Import Options. For more information, see Civil Engineering Data Translator Client Dialog Box.
     Note: Selecting the Triangles option under Surface Import Parameters improves the surface accuracy but reduces the speed of the translation process. When you select the Triangles option, the other options, except Contours, are selected automatically.
7. Click Upload to upload the file and start the translation process.

   A dialog box is displayed to inform you that the data is being transferred to the cloud.

   The status of the translation job is displayed in the Job Monitor section of the dialog box.

8. If you uploaded a GEOPAK GPK file that contains alignments and profiles, two translation stages are required.
   1. When the first stage is complete, Complete (Stage 1/2) is displayed in the Status column.
   2. You can initiate the second stage by clicking Configure Mapping in the Result column. When you click Configure Mapping, the Profile to Alignment Mapping dialog box is displayed. Use the Profile to Alignment Mapping dialog box to associate the profiles with the alignments and click OK. When the second stage is complete, Complete (Stage 2/2) is displayed in the Status column.
9. When the translation job has completed, click Download in the Result column to download the files.
   Note: You can specify a default location for the downloaded files by changing the Job Monitor Configuration settings. Click to open the Job Monitor Configuration dialog box.

Depending on the type of translation job performed, and the data available in the source file, different file types are created during the data translation process, as shown in the following table.

Data Translation Source Type	Source File Type Selected for Translation	Resulting File Types Created During Translation	Object Translation Notes
Bentley GEOPAK Project Data	.gpk	<GPK name>.dwg <GPK name>-gpk.xlsx <GPK name>-gpk.xml	Alignment chains are converted as alignments. Profiles that you assign to alignments using the Profile to Alignment Mapping dialog box are converted as profiles and are associated with the designated alignment. Any unassigned profiles are not converted. Parcels are converted as parcels. Survey chains are converted as 3D polylines.
Bentley GEOPAK Project Data	.tin	<TIN name>.dwg <TIN name>-tin.xlsx <TIN name>-tin.xml	Selecting the Triangles option under Surface Import Options improves the surface accuracy but reduces the speed of the translation process. An XML file is generated for each TIN file that you import. After you download the translated files, you can optionally point the surface in the Autodesk Civil 3D drawing to the corresponding XML file by modifying the surface properties.
Bentley InRoads Project Data	.alg	<ALG name>.dwg <ALG name>-alg.xlsx <ALG name>-alg.xml	Points are converted as points. Alignments are converted as alignments. If an alignment has disconnected segments, the segments are converted as part of the same alignment, and gaps are removed. For example, if the source alignment contains two disconnected lines, during the conversion process the start point of the second line will be adjusted so that it links to the end point of the first line, and the report file will list the difference in the alignment length. Profiles are converted as profiles and are associated with their related alignments.
Bentley InRoads Project Data	.dtm	<DTM name>.dwg <DTM name>-dtm.xlsx <DTM name>-dtm.xml	Selecting the Triangles option under Surface Import Options improves the surface accuracy but reduces the speed of the translation process. An XML file is generated for each DTM file that you import. After you download the translated files, you can optionally point the surface in the Autodesk Civil 3D drawing to the corresponding XML file by modifying the surface properties.
