What type of line is utilized to interrupt a drawing when an object does not fit on the sheet?

A break line is specifically designed to indicate that a portion of an object is omitted from a drawing because it does not fit on the page. This typographical feature helps convey that the drawing has been abbreviated and visually represents that the section is continuous beyond the drawn boundaries. The break line typically has a zigzag or a serrated pattern, which clearly distinguishes it from other line types and signals to the viewer that there is more to the object than what is shown.

In contrast, center lines are used to show the axes of symmetry in parts, hidden lines indicate outlines or edges that are not visible from the current viewpoint, and leader lines are used to connect notes or labels to specific parts of a drawing. Each of these line types serves a different purpose in technical drawings, but it is the break line that effectively communicates the omission of parts that do not fit within the confines of the sheet.
