Specifying Whether or Not to Outdate Secondary Content
The preference category Operation > CAD Data Management > Content Handling > Mark Out Of Date lists the secondary content categories for your site. For each category of file type, if the preference <secondary_content_category> (for example, Instance Accelerator File) is set to yes, it means that upon checking in a content change (not a metadata change) of the CAD document, any secondary content of the specified category type is marked as outdated (for example, in the Attachments table on the CAD document information page). A value of no means that the category does not become outdated as it is carried forward with the CAD document.
You can manually override conflicts caused by outdated files, for example, during a Check In attempt by:
stopping the checkin and manually updating the attachment, thus removing the “outdated” flag.
removing the attachment from the CAD document.
resetting the status (removing the Outdated flag).
overriding the conflict and checking the CAD document in “as is” -- with an Outdated status.
