And what formats are supported?
BIM models are supported via the iModelHub content pipeline. First, syncronize your file to the iModelHub with the iTwin Synchronizer or a ProjectWise connector, then in the OCP editor, click the iModelHub button, select the Connect project that your iModel resides in, and then select the iModel.
If the iModel is updated in the Hub, it will automatically be updated in your OCP project as well.
