Cutting a profile in PowerCivil through an OpenBridge Model


Ive created a model in openbridge and wanted to create a profile along the Rail alignment used that shows the deck piers and ground level.  I was planning on doing this in PowerCivil however I've been unable to reference in the Openbridge model or open it using PowerCivil and get this error.

I am using "Bentley PowerCivil for UK and Ireland V8i (SELECTseries 4)" and "OpenBridge Modeler CONNECT Edition - 2018 Release 2" it seem odd that two Bently products don't work together so i assume its something with the versions I'm using.

If i cant get this to work is there a way to cut the profile in openbridge its self?

Thanks for the help,
