A line used to show alternate positions of an object or matching part without interfering with the main drawing that is made up of one long and 2 short dashes?

A line used to show alternate positions of an object or matching part without interfering with the main drawing that is made up of one long and 2 short dashes?

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

Answer: (A)

Phantom lines are used to show alternate positions or related parts without cluttering the main view. They’re drawn lighter and consist of a series of short, evenly spaced dashes that float near the object, indicating what a part could look like or where another position would be, without changing the primary drawing. This makes it clear how components might fit or move while keeping the main geometry clean. Hidden lines indicate features not visible in the view with short dashes, center lines show axes or symmetry with a long-short pattern, and leader lines connect notes to features. So phantom line is the right choice for illustrating alternate positions without interfering with the main drawing.
