    Best Practices for Creating a Civil iModel

    Product(s): OpenRoads Designer
    Version(s): 10.08+
    Area:  General

    Question: 

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

    Answer:

    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.

    Current Limitations:

    Limitations: Terrains

    • All terrains less than 7 million points will go directly into the iModel.
    • Terrains greater than 7 million points require the use of a Context Data Share which would have to be setup for the project.
    • Be aware that large terrains can greatly increase processing times.

    Limitations: Subsurface

    • If your references contain Drainage & Utilities data, the main container file must have a subsurface project created.
      • e.g. Place a node
    • Results properties (such as Velocity/Depth/Spread) will only be published from iTwin Synchronizer.

    Limitations: OpenSite

    • Currently, OpenSite properties will not be included in the iModel.
