A short break in a long uniform component is shown by a

  • A.short-dashed thin line across the part
  • B.continuous thick line of double weight
  • C.continuous thin line with freehand zigzags
  • D.long chain line with thickened ends

Answer: C

Correct answer: continuous thin line with freehand zigzags

A break line lets a long uniform component be drawn shortened so it fits the sheet, with the dimension stated at its full value. The freehand or zigzag form makes it unmistakably a break rather than a real edge. It may only be used where the omitted portion is uniform, so that nothing is concealed by the shortening.
