Phantom Line is used to show alternate positions without interfering with the main drawing. Which option best describes Phantom Line?

• A. A line used to show the alternate positions of an object or matching part without interfering with the main drawing.
• B. A relatively thin flat member acting as a brace support.
• C. A line used to show the alternate positions of an object without interfering with the main drawing.
• D. An assembly drawing in which parts are moved out of position along an axis.

Answer: (C)

Phantom lines are used to show alternate positions or possible locations of a part without cluttering or altering the main drawing. They appear lighter and broken (dashed) so they don’t interfere with the solid outlines of the object, letting you understand how a part could be placed or moved without changing the primary view. The description that matches this use is a line used to show the alternate positions of an object without interfering with the main drawing. The other options describe a brace-like support or an assembly scenario with moved parts along an axis, which are not what phantom lines represent.
