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.

4. Chain lines: These are used in architectural drawings to represent the location of a joist, rafter, or stud.

5. Construction line: These are light, thin lines used as guides to help create accurate drawings.

6. Continuous thick line: These are bold, solid lines used to show the main outlines of an object or structure.

7. Continuous thin line: These are used for dimension lines, extension lines, and outlines that are not the main focus of the drawing.

8. Cutting plane lines: These are used to show where an object has been cut in a sectional view.

9. Dimension lines: These are used to indicate the size of an object in a technical drawing.

10. Extension lines: These are used in conjunction with dimension lines to indicate the extent of the measured dimension.
