Definition
The title block is the fixed panel on every engineering sheet. It holds the project, owner and office names, the sheet title and number, scale and date, revision number, and the names of the designer, checker and approver.
Why it matters on a project
It tells you which copy is current. A sheet without a clear revision number can be built from an old copy.
Common mistake
Changing a sheet without updating its revision number and date, leaving two different versions with the same number on site.
Frequently asked questions
What goes in the title block?
