I have a project I'm working on and recently imported a model from grabcad.com. Now, whenever I try and edit the project I get the message: "Cannot modify the library file *.iam Component *.iam is not checked out to you. Edits are not allowed on this file." the only solution I could find is purging the files, which I don't know how to do and it was supposedly removed in the 2013 update anyways. I also get a message "The file is being saved in a library folder. Because files in a library folder are not editable, once you save this file you will not be able to modify it. Do you wish to continue?" I have tried saving everywhere, even the C drive (which is obviously not a folder to begin with). What have I done? And how can I fix it?
I suspect that the import destination file location is causing an issue here, you might provide more information about the file paths, including your Inventor Project path, and maybe some screen shots.
They are both (importer and importee) saved in Public Documents, but I have tried moving them to every other place I can think of (Desktop, C Drive, flash drive, etc), Even after deleting the component that resulted in the problem, the message persisted. Unfortunately, I have made no backups that don't have the same problem. I think it's more of a Vault problem. I was creating the project unconnected to Vault and the object I imported was "claimed." I think somehow it took over my project. Does that help at all?
