Often times when reviewing CAD files, I find the previous person has left an old STEP file, or other attachments on the CAD object. This can be removed in a workspace, but it would be nice to be able to just remove it from the table in the general "commonspace" view, the Attachments list on the content tab.
Since attachments are largely unseen inside Creo unless you go look for them, they typically go unnoticed until they are looked at in Windchill.
