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

  1. In Toolspace, on the Toolbox tab, expand Subscription Extension Manager Autodesk® Civil Engineering Data Translator 2015.
  2. Double-click one of the following commands:
    • Import Bentley GEOPAK Project Data: Use this command to translate TIN and GPK files to files that can be used in AutoCAD Civil 3D.
      Note: Each file must be selected separately, so to translate both a TIN file and a GPK file, the command must be run twice. Each time you run the command, a separate AutoCAD Civil 3D drawing is created. You can use data shortcuts to link the data in the resulting drawings together.
    • Import Bentley InRoads Project Data: Use this command to translate DTM and ALG files to files that can be used in AutoCAD Civil 3D.
      Note: Each file must be selected separately, so to translate both a DTM file and an ALG file, the command must be run twice. Each time you run the command, a separate AutoCAD Civil 3D drawing is created. You can use data shortcuts to link the data in the resulting drawings together.
  3. If you are not currently logged in to Autodesk 360, the Autodesk 360 Login dialog box is displayed. Use the Login dialog box to sign in, or click Need an Autodesk ID? to create an account.

    The Open dialog box is displayed.

  4. In the Open dialog box, select the file to translate and click Open.
    Note: In order 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 #.
  5. At the Command line, enter the unit type of the source file.
  6. If you selected a TIN or DTM file to translate, the Surface Import Settings dialog box is displayed. Specify the surface elements to import and whether to create a surface snapshot after import.
    Note: Selecting the Triangles option in the Surface Import Settings dialog box 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 OK.

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

  8. In Toolspace, on the Toolbox tab, expand Subscription Extension Manager Autodesk® Civil Engineering Data Translator 2015. Double-click Open Job Monitor.

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

  9. If you selected a GEOPAK GPK file that contains alignments and profiles, (Stage 1/2) will be displayed as part of the information in the Status column. When stage 1 is complete, you can initiate stage 2 of the conversion 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.
  10. When the 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. For more information, see Job Monitor Dialog Box.

Depending on the type of 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.

Command Source File Type Selected for Translation Resulting File Types Created During Translation Object Translation Notes
Import 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.
Import Bentley GEOPAK Project Data

.tin

  • <TIN name>.dwg
  • <TIN name>-tin.xlsx
  • <TIN name>-tin.xml
  • Selecting the Triangles option in the Surface Import Settings dialog box 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 AutoCAD Civil 3D drawing to the corresponding XML file by modifying the surface properties.
Import 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.
Import Bentley InRoads Project Data

.dtm

  • <DTM name>.dwg
  • <DTM name>-dtm.xlsx
  • <DTM name>-dtm.xml
  • Selecting the Triangles option in the Surface Import Settings dialog box 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 AutoCAD Civil 3D drawing to the corresponding XML file by modifying the surface properties.
