AutoPLANT i-model, which Navigator version

Hi,

AutoPLANT SS7r1 (.239)

AutoPLANT i-model Composer (.129)

ProjectWise SS4 (.590)

Navigator Connect (6.1.1.52)

I'm trying to view an i-model created from a piping model. Navigator shows error message saying that MicroStation Connect update 3 need to be used. So my question is which version of Navigator I should use?

PS I'm trying to setup iCS to automate i-model from our entire project. Am I wasting my time?

Thanks,

SH
