Rogue dimensions in Revit Insert Link CAD

I often use the insert Link CAD process to bring in an AutoCAD drawing to overlay my work. I'm using Revit 2020 from the Building Design Suite Premium package.

 

I am inserting an AutoCAD file that originated from the civil engineer. When I look at the file in AutoCAD 2020, I can zoom to the project extents which is several hundred feet. After I link it to Revit and zoom in within Revit, the extents becomes 225,000 feet. It looks like the insert process splits out the dimensions in the AutoCAD file and moves them northwest 225,000 feet away from the entities they measure. I never had this happen to me before. I tested this in Revit 2019, and got the same behavior.

 

Anyone know what's going on?

 

If I go into the AutoCAD file and remove the dimensions before linking to Revit, I can then zoom to the project extents.

The AutoCAD site plan given to me takes up no more than several hundred feet. When I insert it into Revit, the dimensions separate from the site graphics and fly away from their original positions by 225,000 feet. I have never experienced this before. I don't know what you mean that the maximum distance limit was exceeded. There was no excess I could see in the AutoCAD file.

It is possible that what you see in the AutoCAD drawing is not very large (when you zoom to extents), but the extents may be very far away.  This occurs when location data is included in the CAD.  Check in your CAD file and ID an element, which will show the internal coordinates for that object or intersection.

Agreed. I had a civil site cad file provided once for a project where the origin was set to be over 2,000 miles away. After convincing the engineer that this was sloppy drafting, they provided an updated dwg without 2,000 miles of empty space and everything worked again.
