I'm seeing an issue where Revit keeps giving me a warning that linked objects are too far from the the origin when linking AutoCAD and defaulting to center-to-center. The odd thing is that all of the CAD linework has been moved to be right on the 0,0 point in the file and not other shared coordinates, or named UCS are being used. The CAD drawing is a large site, but there are no elements that exceed 2000ft from the origin which is well within the 20mi limit in Revit. Furthermore, in attempting to work around this glitch, I tried to link the CAD via a manual origin, but none of the snaps are obeyed when trying to place! This should definitely not happen! I've already purged and audited the CAD to make sure there is no hidden or other geometry. For all intents and purposes, the CAD to be linked is perfectly legit and should have absolutely no issues linking directly via origin-to-origin. Does anyone have any insight on what might be causing this glitch? Is there another, smaller extent limitation that is unstated within Revit preventing it from working correctly? Thanks.

First, whenever possible, I always like to wblock out just the elements I need with a new origin.  That solves 99% of the problems.

Second, there may be other elements in that dwg that have their own origins.

The blocking idea is something I hadn't tried. I did check the other blocks in the drawing and they all have origins that are coordinated to logical portions of their geometry. Another annoying thing. But I have a feeling what you suggested is going to work. Thank you sir!

Can I replicate the behavior of an dynamic block (autocad) in a revit family?
