What type of line is typically used to indicate a break or interruption in a drawing?

The type of line used to indicate a break or interruption in a drawing is the break line. Break lines are specifically designed to show where a section of detail has been removed from the drawing to allow for clarity and to focus on specific areas without having to depict the entire length or extent of an object. This technique is particularly useful in complex designs where space is limited or where long objects would otherwise dominate the drawing without adding useful information.

In contrast, leader lines are used to indicate the dimensions of an object or to point to a particular note or feature. Dimension lines convey measurements and relationships between different parts of the drawing. Hidden lines show features that are not directly visible from the current view, often represented by dashed lines. Each of these line types serves specific functions within technical drawings, but break lines uniquely denote discontinuities or separations, guiding the viewer's understanding of the design without cluttering the drawing.
