What does it mean when a sketch is over dimensioned?

• A. The same dimension is on 2 or more of the views.
• B. The sketch uses metric units only.
• C. The dimension lines are too thin.
• D. The dimensions are all integers.

Answer: (A)

Over-dimensioning happens when the same measurement is repeated in more than one view of a sketch. In a well-dimensional drawing, you provide just enough dimensions to fully define the part, without duplicating measurements across views. When a dimension appears in multiple views, it’s easy for the values to drift apart if the part is adjusted or if the views aren’t perfectly aligned, which creates clutter and potential inconsistencies. Keeping dimensions to a single, clear definition for each feature reduces confusion and errors. The other options describe unrelated drawing details—unit system, line thickness, or whether numbers are integers—none of which describe redundancy or duplication of measurements across views.
