Maybe I should clarify. We had surmised that the rotation was to address
the y-up vs.
z-up differences between Inventor and performer but we didn't want it for
various reasons.
We are now investigating our options for eliminating it within the context
of our simulations.

Just to be sure that the obvious is not overlooked, people might want to
be sure that the 90 degree rotation they are getting is not due to the
difference between Inventor's y-up and Performer's z-up assumptions,
i.e., sometimes you get what you asked for and it's not what you wanted.
