I keep receiving this error on a very large teamwork project, causing all work done since last send/receive to be lost, unless I save down and manually copy elements/changes over to the teamwork file. How did you determine which object was giving you issues? This is a very large teamwork file and I can't delete elements one by one.
We have recently migrated the project to AC22, and in that process, saved down and open/repaired the file before migrating.
Thanks in advance!
Make sure you have your work environment set to write reports. Then go to the 3D window and turn all layers/filters on and you'll most likely be interrupted with an error report which will tell you which part of the model is having issues.
It may be a model element such as a mesh/slab or it may be part of a library object which is generally a little trickier to fix.
Thank you for the help. Turns out there were a lot of repeated errors in the report, and a lot of sneaky degenerated elements that I had to hunt down and eliminate. But great success! No more crashes since. Thanks all.
