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

• Drainage & Utilities data that is shown in the Civil properties will be included
• The iTwin Synchronizer will also include properties from the Drainage & Utilities databases

Limitations: OpenSite

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