What type of line would be used to shorten drawings for extremely long parts?

• A. Break line
• B. Dimension line
• C. Leader line
• D. Extension line

Answer: (A)

A break line is used to shorten drawings for very long parts by truncating the view and signaling that a portion is omitted. This keeps the drawing readable on a standard sheet while showing the essential features and overall length. Break lines can be drawn as a jagged zig-zag or a smooth wavy line to indicate the portion isn’t shown. This is different from dimension lines, which show measurements; extension lines, which project the dimension away from the object; and leader lines, which attach notes or callsouts to features. In practice, breaking the view is the standard way to represent a long part without losing important details.
