We have been seeing problems with DWG files that no longer open completely in RHINO. What I mean is that certain objects in the DWG just disappear. They open fine and completely in AUTOCAD.

Hi Walt - [image] wm_c: I can upload to McNeel support directly, if requested. Yes, we’ll need to see the DWG file to find out more about this. You can use https://www.rhino3d.com/upload to upload it - make sure to copy the URL to this thread in the comments field. Thanks, -wim

Thank you, Wim. I have uploaded the file and added the URL to the comment.
