As for now, you only have the ability to publish your Revit models to ACC, ACC then automatically uses the shared coordinate system within Model Coordination.
However, we are working with a lot of different kind of models (Plant3D, Civil3D, Aveva etc) and not every software package has the option to switch between coordinate systems.
For example, if we setup a project in Revit we are mostly using Internal Origin to exchange models between different software packages. Behind this Internal Origin there is the Shared Coordinates system (for our company mostly RD coordinates, which is a projected coordinate system for Netherlands).
If ACC Model Coordination is always using the shared coordination system then there will be huge differences in positions of models. Without having the ability to switch between these coordinate systems, you have to manually move a model to the right position, which costs a lot of time, not to mention that manually moving models is prone to error.
What we basically need or would love to see in the future is the option to switch between Internal Origin and Shared Coordinates within the Model Coordination on ACC.
