QUESTIONA mechanic prepares a sketch from which a replacement part will be manufactured. How complete must the sketch be?

  1. AA pictorial outline is enough because the shop sets the dimensions
  2. BIt must show all necessary construction details
  3. CIt needs only the overall dimensions and the material
Show the answer and explanation

Correct answer: B. It must show all necessary construction details

  • A — incorrect A sketch that need not be dimensioned is one used only to represent an object pictorially, not one used to manufacture a part.
  • B — correct The handbook states that if a part is to be manufactured from the sketch, it should show all the necessary construction details.
  • C — incorrect A manufacturing sketch must provide all information needed to make the part, not only the overall size and material.

BACKGROUND

A sketch is a simple rough drawing made rapidly and without much detail, and a mechanic may need one to present a new design, a modification, or a repair method. A sketch is frequently drawn for repairs or for use in manufacturing a replacement part, and such a sketch must provide all necessary information to those who must make the repair or manufacture the part. The degree of completeness depends on the intended use. A sketch used only to represent an object pictorially need not be dimensioned, but a part to be manufactured from the sketch requires all necessary construction details.

STUDY TIP

Decide what the sketch will be used for first; a manufacturing sketch has to carry everything the maker needs.

KEY POINTS

  • Repair sketches must give all information needed by those making the repair or part.
  • Completeness depends on the intended use of the sketch.
  • A sketch used to manufacture a part must show all necessary construction details.
