Moving the Project Base Point

David Baldacchino tweeted today that he has proof that Revit doesn't like geometry far away from the origin of the project file, specifically 10 mile radius from the origin. He provided an image of this warning message.

I have to admit I've never tried moving the project base point that far. I guess I've been indoctrinated to play inside my 10 mile radius sandbox? Be prepared to get your hand slapped by Revit if you try it.

Steve, I found out today that if you move the Project Base Point using the little X-Y axes arrow controls, Revit won't know/bother you about being outside this radius. I would consider this to be a bug because if it is truly an issue, it should detect it regardless of how you move the PBP around. Moving a clipped Survey Point (which moves the Shared Coordinate system around) does not have this limitation. For kicks I moved it to the moon (no really, 250,000 miles from the internal origin) and it all seemed to work, until I got close to my geometry and couldn't zoom in further! So you could use a geodetic marker placed on the moon I suppose, but use caustion as you might not be able to zoom in enough to work :) (PS: the moon moves!).

Thanks for the update!

Just an FYI, it appears there has been an update to 2014 that has expanded that limitation to 20 miles.
