Very disturbing xref bug

Over the last few months I have experienced several worrisome occurrences of an xref "shifting", but with insertion point, x/y/z scale, and units all matching the host drawing - all these established from the point of referencing.  This has occurred with 2 separate projects, on 2 separate machines, on two versions (2022 and 2024).   The only solution I've found is to detach and reattach, which blows out all xref overrides.  The shift is about a foot or two.

 

Has anybody else experienced this?  Is there a TS'ing step that I'm not utilizing?

I don't think I have seen this but I can give you a couple of potential causes.  Based on what you are describing, it sounds like this.

 

Often times people will try to select objects and accidently drag an object (xref) over a bit.  One way you can avoid this is to use the XREFLAYER setting and pick a layer for xrefs to be 'inserted' on.  (We use _XREF).  Once the xref is overlaid into the file, you can lock the _XREF layer.  That work fairly well for locking these down.

 

If you do that with an xref on a locked layer, you will get: 1 was on a locked layer.

I spend time on this forum because I enjoy Civil 3d and getting your likes.

This is disturbing indeed.  The last thing anyone wants is unexplained creep in a design drawing.  I agree with @brian.strandberg  that locking layers might be a solution, I’d be interested to know if this stops the creep.

 

As for the cause of the creep, I am not sure.  Potentially a junior cad user?  I found one of our new users moving objects to select objects beneath because they did not know about the selection cycling feature.

This will occur if the host drawing is set to feet and the xref is set to survey feet. But it does sound like and inadvertent flick

 

Why I cant explain but it does

Try choosing Unitless for insertion scale in Units
