What does a gray border around a drawing view indicate?

A gray border around a drawing view signifies that a part or assembly has changed since the last time the drawing was updated. This visual cue alerts the user that there may be discrepancies between the drawing and the actual model components, prompting them to update the drawing view to reflect the latest changes. It serves as a critical reminder to ensure that all representations within the drawing accurately reflect the current state of the design, which is essential for maintaining clarity and accuracy in documentation.

While a drawing view being marked for revision, being reviewed, or being up to date are all important aspects of managing drawings, they do not specifically relate to the presence of a gray border. This border is uniquely indicative of changes that have not yet been captured in the drawing, emphasizing the importance of regularly syncing drawings with their respective models to avoid confusion or errors in design communication.
