Break lines are used in architectural drawings to indicate that a portion of an object has been removed or "broken off" in order to save space in the representation and make the drawing clearer. This is particularly helpful when an object is too long to be fully drawn in a limited area, and instead of drawing the entire length, a break line shows that part of the object is omitted. This technique allows for a more efficient use of space on the drawing without losing the overall understanding of the object’s dimensions and shape.

In contrast, other choices suggest functionalities that break lines do not typically serve. For instance, they do not measure elevation changes, provide space for notes, or indicate utility connection points. Each of these functions is addressed through different symbols or annotations within architectural and engineering drawings. Thus, the main role of break lines is to denote breaks in the continuity of an object for clarity and space efficiency.
