Solid objects show as wireframe after conversion into an iModel

Reason: This could be an issue in the source data where the top-level boundary representations (BREP) are missing feature solids.

How to fix: Bentley design applications like MicroStation CONNECT Edition can fix the display of the wireframe in the source data automatically on the opening of the model, however for the MicroStation Connector to process such geometry into an iModel you would need to regenerate the BREP elements in a DGN using the "modeler synchbreps" key-in.

Use these steps to update source data:

1. Open the key-in dialog in MicroStation and enter "modeler synchbreps". 
2. Save the DGN after it completes.
3. The next time the iModel conversion job will be rerun, the element will be fixed.
