Title block content on working drawings Among the following, which item is normally included in the title block so sheets can be tracked across a multi-sheet drawing set?

Introduction / Context:
The title block anchors administrative information for each sheet: identification, ownership, revision history, scaling, and traceability across the set. This meta-data allows project teams to verify they are using the right sheet at the right revision.

Given Data / Assumptions:

• A working drawing set may include many sheets.
• Readers need to navigate and control revisions.
• Standard title block entries include drawing title/number, sheet number, scale, dates, and approvals.

Concept / Approach:
The sheet number is a universal component of the title block (for example, 3 of 12). Line type and layer set are CAD configuration details, typically governed by templates and standards, not recorded inside the title block fields.

Step-by-Step Solution:

Verification / Alternative check:
Cross-check the index sheet (cover) to ensure each sheet number aligns with the sheet listing and revision status.

Why Other Options Are Wrong:

• Line type / layer set: Managed by CAD standards and templates; not typical title block entries.
• All of the above: Overstates what belongs in the title block.

Common Pitfalls:
Omitting sheet numbers or mixing numbering schemes causes field confusion and rework.

Final Answer:
sheet number
