Opening Civil 3D files in microstation - object enablers - install sequence and has anyone had any success?

I am working within a project where Civil3D is mostly being used.
However the structures team are using microstation and aecosim.
Civil 3D is 2015
Microstation SS3
Aecosim SS6

I have installed both civil 3d 2015 and 2016, and microstation.

I have also installed real dwg 2016 and the 2016 object enables from autodesk, yet i still do not get so see the Civil 3D elements.
I believe this is possible and wonder if anyone has accomplished this what their method of install was.

I am really trying to avoid multiple conversions when there shouldn't be any need its a terrible workflow.

All help appreciated.
