CD Quality Assurance & Compliance 2 — Questions and Answers
Question 1: During a drawing check, a drafter finds a dimension that conflicts with a note on the same sheet. According to standard drafting practice, which takes precedence?
- The dimension shown on the drawing (Correct answer)
- The general note
- Whichever was added most recently
- The title block tolerance
Correct answer: The dimension shown on the drawing
Specific dimensions on the drawing govern over general notes when a conflict exists.
Question 2: A revision cloud is used on a drawing primarily to:
- Highlight areas changed in the current revision (Correct answer)
- Mark areas that failed inspection
- Indicate proprietary information
- Show sections requiring engineer approval
Correct answer: Highlight areas changed in the current revision
Revision clouds visually identify the portions of a drawing modified in the latest revision.
Question 3: Which document defines the default tolerances applied to dimensions that have no tolerance explicitly stated?
- The title block or general tolerance note (Correct answer)
- The bill of materials
- The revision history block
- The purchase order
Correct answer: The title block or general tolerance note
Default tolerances for untoleranced dimensions are specified in the title block or general notes.
Question 4: A checker rejects a drawing because a part cannot be inspected as dimensioned. This is most likely a violation of which principle?
- Dimensions should support functional inspection and measurement (Correct answer)
- Dimensions must always be in metric units
- All dimensions must be baseline dimensions
- Every feature requires a datum reference
Correct answer: Dimensions should support functional inspection and measurement
Dimensioning must allow features to be measured and verified during inspection.
Question 5: Under ASME Y14.5, what does applying GD&T to a drawing primarily ensure?
- Uniform interpretation of geometric requirements by all users (Correct answer)
- Faster CAD file loading
- Reduced number of drawing sheets
- Elimination of the need for tolerances
Correct answer: Uniform interpretation of geometric requirements by all users
GD&T per ASME Y14.5 standardizes how geometric requirements are stated and interpreted.
Question 6: Before releasing a drawing package, the drafter must verify that the revision level on each sheet matches the:
- Engineering change order (ECO) authorizing the release (Correct answer)
- Manufacturing schedule
- Inspector's stamp
- CAD software version
Correct answer: Engineering change order (ECO) authorizing the release
Released revision levels must match the authorizing engineering change documentation.
Question 7: A drawing marked 'NOT TO SCALE' next to a dimension means the user should:
- Rely on the stated dimension value, not measurements from the drawing (Correct answer)
- Scale the drawing and average the results
- Ignore that dimension entirely
- Request a full-size plot before using it
Correct answer: Rely on the stated dimension value, not measurements from the drawing
The stated numerical dimension governs; the drawn geometry is not proportionally accurate there.
