Introduction / Context:
Working drawing packages typically include detail drawings (one part per sheet or view set) and assembly drawings. The detail drawing’s role is to communicate everything a competent manufacturer needs to make the part correctly—no guessing and no hidden assumptions.
Given Data / Assumptions:
- All critical dimensions, tolerances, and GD&T are provided.
- Material specification, heat treatment, and finish are stated where applicable.
- Notes list edge breaks, deburring, and any special instructions.
Concept / Approach:
Completeness ensures interchangeability, quality, and legal clarity. If a drawing omits essential information (e.g., material, thickness, hole size tolerance), the part can be misinterpreted, causing rework or field failures. Detail drawings should stand alone, while assembly drawings show how parts relate and include balloon callouts and BOM entries.
Step-by-Step Solution:
Audit the drawing for complete dimensions and tolerances for every critical feature.Add material, finish, and hardness requirements as needed.Include GD&T where functional relationships must be controlled.Verify that inspection can confirm all specified requirements.
Verification / Alternative check:
Ask a manufacturing partner to review: if they can build the part without further questions, the detail drawing is sufficient.
Why Other Options Are Wrong:
Incorrect: Suggests that detail drawings need not be self-contained, which undermines their purpose.Only true for welded fabrications / Applies only to sheet metal: Completeness applies to all part types—machined, molded, printed, cast, or welded.
Common Pitfalls:
Relying on model-only definitions without a clear model-based definition standard.Leaving default title-block tolerances to govern critical features rather than specifying explicit limits.
Final Answer:
Correct
