Which statement about phantom lines is true?

Which statement about phantom lines is true?

• A. They indicate a part in its current fixed position
• B. They depict a broken, interrupted edge
• C. They show a hidden edge behind material
• D. They indicate an alternate position or feature

Answer: (D)

Phantom lines are used to show an alternate position or feature of a part, not its current fixed state. They’re drawn lighter with a distinct dashed pattern to indicate that this outline represents a movement, a different configuration, or a possible location rather than what is actually in the view. For example, you might sketch a door in its open position as a phantom outline to show how much it would swing or how another part would interact. This helps communicate how parts could relate or fit together in different configurations without making the drawing cluttered with multiple solid outlines. They aren’t used to indicate the part in its current position (that would be drawn with solid visible lines), they aren’t a broken edge indicating a break in the part, and they aren’t the hidden lines that show edges not visible in the view behind material.
