Which line type is typically used to indicate the path of motion for a part that is not currently in its new position?

• A. Phantom line
• B. Center line
• C. Hidden line
• D. Leader line

Answer: (A)

Phantom lines are used to show movement and alternate positions in drawings. They’re drawn lighter and with a dashed style so you can see where a part would move or where it would end up without using the actual current position. This makes the path of motion clear while keeping the real position visually separate. Center lines mark axes or symmetry, hidden lines indicate features not visible in the view, and leader lines point to notes or dimensions—each serving a different purpose.
