Referencing this post does anyone have any new information or a better workaround for checking in file types that Vault defines as "design files" but that we have no addin to check them in from. This is a fairly major problem that I know of no good workaround for. There is a post in the idea exchange that has been acknowledged by Autodesk. Please go HERE to that post and ADD KUDOS to get more attention for this issue. Thanks,
