Dimensions and Multileaders randomly fly into space

[robert3DCM5]

I'm having an issue that, like the title says, effects random dimensions and multileader notes.  It seems to happen when reloading an Xref, or when opening a drawing after editing a file that is referenced.

I would understand if the notes in question were directly associated with any linework that was edited and reloaded, but typically isn't.  I could editing something in one area of the drawing with no direct correlation to notes that fly off on the other side of the drawing.  There seems to be no rhyme or reason to why it's happening.

This is odd...I've only seen this happen when there may be objects placed by mistake on another z axis.

Perhaps try either the RECOVER command to open the dwg or the AUDIT command while in the dwg to see if that may fix this.

I should have mentioned that it's happening in multiple files for multiple projects.  In this particular project there is a possibility of something getting associated to a different Z axis, but in the other projects this has happened in they are purely 2D conceptual site plans.

@robert3DCM5 If the issue is unique to one drawing or a set of drawings but never in any other of your files, it could be a workflow or as you noted something else unique to them.

Your dimensions and mleaders are associative and snapped to points on your XREF I assume: reloading your XREF may have shifted those points, or the reload delay may be enough, your dims and mleaders can be triggered to "bounce" away afterwards.

Are you by chance editing your XREFs using REFEDIT command? or the longer way with XOPEN and reloading the XREF? Try the other method and see if you can get them to bounce again.

I use REFEDIT on occasion for quick edits, but in general have my reference files open and reload when needed. 

I would say most are snapped to points in a reference, and once and awhile some are snapped between the reference and a line in the active file.

I asked a co-worker if he's seen the issue and it happens to him to, and we are generally working on different projects.

I had a bad experience once where REFEDIT irreparably corrupted all of the dynamic blocks in a file.  I never found the cause and the blocks were part of a standards set we were provided from a county for their improvements project, so I don't what their history was when we got them.  It's made me wary of the REFEDIT since we have our own dynamic blocks.

@robert3DCM5 I feel the same away about REFEDIT with XREFs: I do what you do.

I suspect your associated dimensions are losing their connection points and why they may bounce occasionally: a DIMREASSOCIATE is the slow way to put them back. No built-in tool for MLEADERs though.
