How to use the Generative Components for ORD?

Hi ,

The latest Openroads Designer and OpenBridge Modeler have included the Generative Components(computational design) ,

But  could you please tell us how to use , and what are the key features?   

Can I use the GC node to control the civil modeling or corridor modeling now?     just like the Dynamo for Civil 3D.

Whether the OpenRoads development team have the plan to develop GC node for OpenRoads/OpenBridge ?

Thanks !
