Final answer:
The latest revision date on a set of blueprints is found on page ii, indicated by a red square within the text marking changes and listed in the Changes and Corrections section.
Step-by-step explanation:
The latest revision date on a set of blueprints can be found in the Changes and Corrections section of the blueprints, specifically on page ii. In electronic versions, any adjustments made to the text are indicated by a red square which is hyperlinked to an entry that outlines the details of the change.
This entry also includes a hyperlinked page number that facilitates easy navigation back to the specific change in the text. Moreover, if the blueprints have undergone substantial updates, the edition number may increase, whereas minor edits may only trigger an increment in the version number. Lastly, the Publication Date section highlights the most recent date of publication, following any updates, in red coloring.
