Engineering drawings — tracking updates and accountability On a released technical drawing, which specific table should document what changes were made, the date of the change, and the person or authority who approved it?

Introduction / Context:
In engineering and architectural documentation, version control is critical. When a drawing is revised after release, stakeholders must know exactly what changed, when it changed, and who authorized or executed the change. This is managed through a dedicated table that serves as an auditable history.

Given Data / Assumptions:

• A formal drawing has been issued (released) to manufacturing or construction.
• Subsequent modifications must be traceable.
• Standard drawing sheet conventions (title block, notes, and revision areas) are used.

Concept / Approach:
The “Record of revisions” (also called a revision history table) consolidates change data in one place. Typical columns include: revision letter or number, brief description of change, affected zone/sheet, date, drafter/checker initials, and approving authority. This table ensures configuration control across departments.

Step-by-Step Solution:
Locate the revision table near the title block or in a designated corner of the sheet.Enter a new revision identifier (e.g., Rev B) whenever a change is made after release.Add a concise description such as “Updated hole diameter from 8.0 to 8.5”.Record the date, drafter/checker initials, and the approver’s sign-off.Cloud and tag drawing changes per company standard to cross-reference the table entry.

Verification / Alternative check:
Cross-check the revision cloud/triangle callouts on the drawing with the table’s entry. The latest revision letter in the title block must match the top entry in the Record of revisions.

Why Other Options Are Wrong:

• Portable document: a file format, not a change log.
• Title form: identifies the drawing but does not detail changes.
• Revision drawings: ambiguous term; the formal trace is the Record of revisions.

Common Pitfalls:
Forgetting to update the title block’s revision letter, vague change descriptions, or missing approver initials undermine traceability.

Final Answer:
Record of revisions
