1. Continuous Line: A continuous line is a solid, unbroken line used to outline the main features of an object. Example: outline of a building in an architectural drawing.
2. Hidden Line: A hidden line is a dashed line used to represent edges or features that are not visible in the current view. Example: hidden edges of a mechanical part in an engineering drawing.
3. Center Line: A center line is a long, dashed line used to indicate the center of a symmetrical object or feature. Example: center line of a shaft in a mechanical drawing.
4. Construction Line: A construction line is a light, thin line used to help in the layout and construction of a drawing. Example: construction lines used to establish the overall dimensions of a floor plan.
5. Dimension Line: A dimension line is a thin, solid line with arrows at each end used to indicate the size or distance of an object or feature. Example: dimension line showing the length of a beam in a structural drawing.
6. Extension Line: An extension line is a thin, solid line used to indicate the points from which a dimension is measured. Example: extension lines used to connect a dimension line to the object being measured.
7. Cutting Plane Line: A cutting plane line is a thick, dashed line used to indicate where an object is cut in a sectional view. Example: cutting plane line showing where a part is cut in a cross-sectional view of a machine component.
2. Hidden Line: A hidden line is a dashed line used to represent edges or features that are not visible in the current view. Example: hidden edges of a mechanical part in an engineering drawing.
3. Center Line: A center line is a long, dashed line used to indicate the center of a symmetrical object or feature. Example: center line of a shaft in a mechanical drawing.

Types of Lines in Technical Drawing
1. Visible Lines (Thick)
- Used to represent visible edges and outlines of an object.
- Example: Outline of a machine part or a building.
2. Hidden Lines (Dashed)
- Used to represent hidden edges and contours not visible from the current view.
- Example: Inner holes or cavities in a machine part.
3. Center Lines (Short Dashed)
- Used to represent the center of circles, arcs, or other symmetrical features.
- Example: Center line of a shaft or hole.
4. Construction Lines (Thin, Long Dashed)
- Used to construct the geometry of the drawing and are not visible in the final drawing.
- Example: Lines used to define perpendicular or parallel relationships.
5. Extension Lines (Thin, Solid)
- Used to extend visible or hidden lines to dimension lines or notes.
- Example: Lines extending from corners to dimension lines.
6. Dimension Lines (Thin, Solid, with Arrows)
- Used to specify the measurements of an object.
- Example: Lines drawn parallel to a surface indicating its length, width, or height.
7. Leader Lines (Thin, Solid)
- Used to connect notes or dimensions to the appropriate features on the drawing.
- Example: Lines with arrows pointing to specific points or areas.
8. Hatch Lines (Thin, Short, Parallel)
- Used to indicate the material or texture of a surface.
- Example: Cross-hatched lines for metal or solid fill for concrete.
9. Break Lines (Zigzag)
- Used to shorten long or complex objects in a drawing.
- Example: Break lines used to represent a section of a pipeline.
10. Section Lines (Thin, Solid)
- Used to indicate the cut surface of an object to show its internal structure.
- Example: Lines drawn perpendicular to the cut surface, indicating the different materials or components.
