Technical Drawing — CAD systems generally make drafting edits, iterations, and corrections faster and less error-prone than traditional board drawing, improving productivity and revision control.

Introduction / Context:
Computer-Aided Design (CAD) transformed drafting by enabling quick edits, associative dimensions, reusable libraries, and digital revision tracking. Compared with manual board drafting, CAD accelerates corrections and reduces compounding errors during rework.

Given Data / Assumptions:

• CAD provides features like layers, blocks, parametrics, and constraints.
• Revisions, version control, and digital markups streamline change cycles.
• Standards templates and title blocks can be enforced automatically.

Concept / Approach:
Associativity and parametrization mean a single edit can update multiple views and dimensions simultaneously, preventing inconsistencies that are common when redrawing by hand.

Step-by-Step Solution:
1) Identify the required correction (dimension, feature, or note).2) Modify geometry; linked dimensions update automatically.3) Regenerate views; verify constraints and standards.4) Save with a new revision; share digitally for review.

Verification / Alternative check:
Time studies routinely show faster turnaround for CAD-based edits versus manual erasing, redrawing, and re-dimensioning on boards.

Why Other Options Are Wrong:
“Incorrect” ignores well-documented productivity gains; “Only true for 3D models…” is wrong—2D CAD also benefits; “True only without standards” and “Depends exclusively on screen size” misunderstand key drivers of efficiency.

Common Pitfalls:
Mismanaged layers or constraints can create confusion; adhere to CAD standards and naming conventions to maintain clarity.

Final Answer:
