The line that signifies the edge of a material in a drawing is known as what type of line?

The term that defines a line indicating the edge of a material in a drawing is referred to as a visible line. This type of line is essential in technical drawings as it outlines the contours and boundaries of the objects being represented. Visible lines are typically solid and bold, making them easy to distinguish from other types of lines used within the drawing.

In contrast, construction lines are generally lighter and used for initial sketches or layout guides, not for outlining the final edges of components. Hidden lines are dashed and indicate features that are not visible from the current viewpoint, while center lines are used to denote symmetry within a part and are typically represented by alternating long and short dashes. Understanding these different line types is crucial for interpreting and creating technical drawings accurately.
