Katkoviivapisteviivayhdistelmä, also known as the dash-dot line, is a type of line used in various fields such as engineering, design, and cartography. It is characterized by a pattern that alternates between short dashes and short dots. The dash-dot line is often used to represent specific types of boundaries, boundaries of secondary importance, or to indicate a less prominent feature compared to a solid line.

In engineering and technical drawings, the dash-dot line is typically used to denote hidden or imaginary lines, such as the edges of an object that are not visible from the current viewpoint. This helps in visualizing the three-dimensional shape of an object on a two-dimensional drawing. The line is also used to represent the boundaries of secondary importance, such as the edges of a hole or a cutout in a material.

In cartography, the dash-dot line is used to represent various features such as contour lines, roads, or other less prominent boundaries. It helps in distinguishing these features from more important ones, which are often represented by solid lines.

The dash-dot line is a versatile tool in various fields, providing a clear and concise way to represent specific types of boundaries and features. Its use depends on the context and the conventions of the field in which it is applied.
