1. Break lines: These are short, wavy lines used in technical drawings to indicate that a portion of the object has been intentionally omitted for clarity.
2. Center lines: These are long, thin lines used to indicate the center of a circle, cylinder, or other symmetrical object.
3. Thin lines: These are used for outlines, hidden features, and other details that are not the main focus of the drawing.
