Final answer:
The revision history area of a document often indicates the eco number, allowing for a more detailed explanation of changes in an external document.
Step-by-step explanation:
True or false: The revision history area of the print often indicates the eco number so a more detailed explanation of changes can be contained in a document external to the drawing.
In the electronic version of a document, changes and corrections are usually listed in a specific section, indicating modifications made since the original release. These changes are marked by a red square that is hyperlinked to a corresponding entry, providing a more detailed explanation. The entry may also include a page reference for easy navigation.
Therefore, the statement is true. The revision history area does indicate the eco number and the detailed explanation of changes can be found in an external document.
