Acquired Coordinates in Revit don't match Autocad survey

[Anonymous]

When I click ID on a point in the Autocad survey file it shows the correct coordinates based on the Indiana State Plain system we are using. I link the file into a brand new clean Revit file then click on "Acquire Coordinates". If I do a spot coordinate for that same spot I checked in ACAD, the coordinates do not match...in fact its exactly double in both directions.

I drew a line in CAD from the origin to a point on the plan, saved and reinserted the model into Revit. When I check the coordinates initially in Revit they are correct but when I hit "Acquire coordinates" the issue arises again and the coordinates are off by double again. Why does ACAD show the correct coordinates but its wrong in Revit after using "Acquire Coordinates"? I've done shared coordinates many times and never have seen this issue.

The image attached is of the plan in Revit showing the line I drew. The blip in the upper right corner is the survey info. The lower left corner is the origin. The numbers shown in the lower left are what it should be reading in the upper right. Instead the upper right is double the numbers shown in the lower left.

I just had a situation exactly as you explained where the Civil File was set up with Ohio State plane coords south Zone NAD83.  When i brought into Revit and Acquired Coordinates i was getting values that were Double what they were in CAD file.  After racking my brain for a few hours i discovers 2 solutions.  The first, was if i wblocked out the site drawing to a new file and brought it into Revit everything worked perfectly.  The Second was i had a person open the file in Civil 3D and reassign the Ohio State plane coordinates and once they did that it came into Revit and worked fine.  So my conclusion was that someone opened the Civil 3D file in a AutoCAD MEP or AutoCAD and did something with the geolocation.  Hope this helps

old thread, but I was having the same issue. 

I found for me, the fix was to set the AutoCAD file to Feet instead of US Survey Feet. The hint for me was that things were just about 6 feet off, which in state plane coordinates (Eastern Missouri for this project) is about the difference in Feet and US Survey Feet.
