Study Notes
Engineering Drawing Lines
- Object lines are heavy, solid lines that outline the visible parts of an object.
- Hidden body lines are medium, broken lines (short dashes) that show hidden features.
- Phantom lines are light, broken lines (short dashes) that show the alternative position or movement of a part.
- Center lines are light, solid lines made of alternating long and short dashes, indicating the center of an object or a feature.
- Extension lines and dimension lines are light, solid lines used to extend from object features and show measurements, with dimension markings placed on the dimension line.
- Leader lines are light, solid lines ending in arrowheads to indicate a specific point on an object.
- Cutting plane lines are heavy, broken lines with arrowheads, indicating an imaginary plane for showing a cross-section, with arrowheads pointing towards the viewing direction.
- Section lines are light, solid lines used in cross-sections, showing a pattern that is typically 45 degrees and varies in style depending on the material.
- Break lines for wood and metal are heavy, freehand or zig-zag lines used to shorten the representation of long, continuous spans.
- Break lines for piping are heavy, curled lines used to abbreviate longer pipe sections.
- Line weights (heavy, medium, light) are approximate and can differ based on drawing scale and style.
- Materials like steel, copper, brass, cast iron, and lead are frequently depicted using specific hatching patterns in section view drawings.
