Hi,

Something strange is happening.

When I link a revit model to another revit model via 'origin to origin', it doesn't appear to be in the right place, just slightly off by approximately 4m. When I link a model I go to a plan view and make sure the orientation is 'true north'.

When I link the revit models via 'shared coordinates' it comes in perfectly.

We have been linking our CAD files to the model 'origin to origin' and we want to keep it that way.

When I link the CAD files to either of the revit models via 'origin to orgin' it comes in perfectly.

The problem only occurs between linming the revit models 'origin to origin'

Does anyone know what is happening here?

Origins in Revit are not the same as CAD.  You can read up on Revit origins in one of the old AUGI Edges magazines - probably 4 years ago....   If the Revit files are a copy, the origin works but shared coordinates is always the preferred method.  AND - Linking CAD origin to Revit origin makes absolutly no sense at all.  CAD file origins can be set - as far as I know, there is no way to set Revit origins.  ...

What this video to learn more about Revit project and survey settings and how to use these.

Re-reading that 2009 article .... there is a way to find Revit's origin.   Read the article here:
