I understand that you can attach a pdf to a part file through the Vault client and manage using revisions. It would be great to be able to do the same from inside Inventor so that the files both check-in together when the workflow is performed. Also, if the user is not using a Vault, it would be great if the file could be attached and/or embedded to the part file/assembly/drawing etc. Maybee an attachment option in iProperties dialogue box or an embedded feature option like the workflow used for adding images to a face prior to creating a decal but of course for use with a datasheet in PDF format.
