I work for a moderatly large company that designs offshore drilling platforms. When setting up our sheets we xref all our primary files in ie: lighting fixtures, receptacles, cable trays, electrical panel, and so on. Recently we have been haveing a problem with some files getting corrupt. No one opens our core files we just xref them in so how could our core files be getting corrupt. Another question is if a file im working on gets corrupt will it corrup all the attached xrefs.
