Which type of line is used to interrupt a drawing if an object will not fit on the sheet?

A break line is used in technical drawings to indicate that a portion of an object has been omitted so that the drawing can fit on the sheet without losing important details. This line symbolically shows that the drawing continues beyond the limitation of the sheet size.

Break lines are drawn as a series of zigzag or curved lines to clearly indicate the interruption and differentiate this section from the rest of the drawing. They help maintain clarity in a design or engineering drawing by allowing for a visual representation of an object that cannot be fully depicted within the constraints of the page, facilitating understanding without compromising the integrity of the design information being portrayed.

In contrast, dimension lines convey measurements, construction lines assist in the layout of the drawing, and hidden lines indicate features that are not visible from the current viewpoint.
