Previous versions of Revit 2012 imported point cloud data (.pcg files) by placing the first data set using "center-to-center" alignment with Revit's origin. Subsequent imported point cloud data files could be imported using "Auto - Origin to Last Placed" so they all align with each other. That's okay if where the point cloud data ends up in your project file is arbitrary to begin with. It isn't so fine if you are trying to align it all with a real world survey coordinate.
I'm happy to write that the Service Pack 2 that was released yesterday has altered this condition for the better. In my testing, using the same data set I was using before, I find that Revit respects the actual origin of the point cloud file and subsequent files still work using the "Auto - Origin to Last Placed" option as expected.
When I drop in my little Laser family and move it into position it all lines up nicely! Too bad it was too late for this one...but the next one will be that much easier! Thanks to the team for getting it into this update!
