Best Practices for Creating a Civil iModel

Product(s):OpenRoads Designer
Area: General


How do I prepare my OpenRoads data to be published to an iModel?


  1. Create a 2D container file with OpenRoads Designer.
    • This container file needs to be created from the correct seed file in the Workspace used by the dataset.
    • The container file needs to have the correct GCS for the project.
  2. Attach all needed/required reference files.
    • If the reference file has a default (2D) and default-3D model, attach the default (2D) model only.
    • If the file has only a 2D model(s), attach each desired model as-is.
    • If the file has only a 3D model(s), attach each desired model as-is.
  3. Create a Civil model in the container file that results in the creation of a default-3D
    • e.g. Make terrain active
  4. Review the hierarchy of the reference files. Be sure that ALL required files\models are listed.
    • Ensure the Reference Display = ON for each reference attachment you want to show in the iModel.
    • Set the 3D-Default model within the “container” file to a minimum nesting depth of 1.
