After a site has been granted access to a published drawing, that site must subscribe to the latest version of the drawing in order to open or edit that drawing. In a connected Workshare collaboration, you get the latest version from the owner site over a database connection by using the commands for remote access. In a standalone Workshare collaboration or a connected collaboration where the satellite does not have remote access to the host, you get the latest version from the owner site by getting the latest version from a local directory after the published files have been extracted into a zip file and manually transmitted to the satellite site via e-mail, CD, network share, or so forth.
Drawings are never dynamically linked between sites. That is, the version you view is only the latest version to which you subscribed or the latest version left on your site. If another site has modified the drawing since you retrieved the latest version of a published drawing, you do not see those changes. At sites that have a copy of a drawing but do not own the drawing, a red lock on the drawing icon appears in the List view. This icon indicates that your version of the drawing may not be the most current.
