Unfortunately the files can't be shared as they are US Defense assets and the red tape to be able to do that is insane. Our company also blocks WeTransfer as it's not a secure enough transfer system.
Attached are some images of the errors, maybe that will help a little.
Given the prevalence of the issue in almost all the files I'm working with on this project, I'm seeking some alternative avenues for better models, but would still like to know what the error might mean so I can mitigate issue going forward or relay it to our engineers so they don't keep doing whatever they're doing.
A little more info: These are Catia files that were migrated over to Windchill but left as Catia files (catprod, catpart,etc) So I'm not sure if that is part of the issue, or if it's an age thing as these files date back to like 2006-7.
