Regions disappear when copied or shared

[RobertMyb]

Hi 

I am having issues with the regions in one of my drawing files.

All regions are visible to me, but as soon as I share the file, the other person can not see any regions in the drawing file. No layer is hidden, lines or polylines in the same layer remain visible, but the regions simply don’t show.

I also noticed that if I copy the region and paste it into the same drawing or into a new drawing, it disappears while the copied region remains. See below screenshots for reference.  The blue and green profiles are regions.

I am also unable to explode any regions.

Also if I copy a region into this particular drawing file from a different drawing file, the region shows.  

Any solutions?

greetings @Anonymous
You are going to have to share both the source DWG file and the "broken/not working" destination DWG file here please if you want serious help with the issue. TIA

Please use the LIST command and select one of the regions. Post the results from the command line.

Perhaps try running audit command on the problem dwg
