All entities in Proxy state after opening dwg in same version

[Anonymous]

Hi, I have searched the forums but not found an answer for this other than "you have to start again in a new drawing". 

I saved my .dwg file in 2018 C3D on Friday afternoon, and left it open over the weekend. It is now Sunday and my dwg is showing the following message when I open it:

A couple of things that may have affected this

1. When I got back to my computer today (Sunday) I had lost connection to our server AutoDesk license while C3D was open, and selected the 'Autosave open drawings and close C3D' option that popped up.
2. I tried opening the .dwg in 2018 and got the error message. I tired Auditing the .dwg in 2018, and reopening in 2018 and got the same message.
3. I tried opening it in 2020 and got the same message

I have a lot of C3D objects (alignments, profiles, corridors, feature lines, surfaces) in this dwg and really don't want to have to rebuild all of these.

Any ideas to help get these back?

Thanks very much

I had this happen in a file once. We had to get support from Autodesk. The way we fixed it was to run QSELECT and look for any proxy objects and delete them. The drawing worked fine afterwards. We don't know what it was or how it got created but we know it did not come from a newer version since we were using the latest version available.

P.S. Before you try this, do it in a copy and verify the drawing is ok before you do it in your working copy.

I've got the similar problem with few of my files while working in 2018 version. I've tried deleting through QSELECT, but is was saying  none select after this selections set
