1. Straight lines: These are lines that do not curve or bend, and are used to represent edges, boundaries, or outlines in technical drawings. Straight lines are typically drawn using a ruler or straight edge to ensure precision and accuracy.
2. Curved lines: These are lines that have a gentle or gradual curve, and are used to represent rounded or curved surfaces in technical drawings. Curved lines can be drawn freehand or using a compass or French curve to achieve the desired shape.
3. Dashed lines: These are lines made up of a series of short, evenly spaced dashes, and are used to represent hidden or invisible features in technical drawings. Dashed lines are often used to show the outlines of objects that are obscured by other parts of the drawing.
4. Center lines: These are lines that consist of alternating long and short dashes, and are used to indicate the center of an object or feature in technical drawings. Center lines are often used to show the symmetry or alignment of components in a drawing.
5. Dimension lines: These are lines that are used to indicate the size or dimensions of objects or features in technical drawings. Dimension lines are typically drawn with arrows at each end to show the extent of the measurement, and are accompanied by numerical values to specify the exact size or distance being measured.

1. Object Lines:
- Represent the visible edges of objects in front view, side view, and top view.
- Drawn with solid, thick lines.
- Indicate the actual shape and size of the object.
2. Hidden Lines:
- Represent hidden or non-visible edges of objects.
- Drawn with dashed lines.
- Break into two short dashed lines at the intersection of object lines.
3. Dimension Lines:
- Used to indicate the size or dimensions of an object.
- Drawn with thin, solid lines.
- Have arrowheads at both ends.
- Include numerical values that specify the length, width, or height of the object.
4. Center Lines:
- Indicate the center or axis of symmetrical objects.
- Drawn with thin, dashed lines.
- Extend slightly beyond the endpoints of the object.
- Have center marks at the endpoints.
5. Leader Lines:
- Connect notes, labels, or dimensions to specific points on the drawing.
- Drawn with thin, dashed lines.
- Have an arrowhead pointing to the referenced point or location.
- Represent the visible edges of objects in front view, side view, and top view.
- Drawn with solid, thick lines.
- Indicate the actual shape and size of the object.
2. Hidden Lines:
- Represent hidden or non-visible edges of objects.
- Drawn with dashed lines.
- Break into two short dashed lines at the intersection of object lines.
3. Dimension Lines:
