Question

break lines are used to show that ______. only part of an object is represented to save space an object will appear in a separate drawing an object is not included on the cutting line view an object is hidden

Explanation:

Break lines are a common feature in technical drawings. Their primary function is to indicate that only a portion of an object is being depicted. This is often done to save space on the drawing sheet while still conveying the necessary information about the object's shape and structure. For example, in a long mechanical part like a shaft, instead of drawing the entire length (which might be unnecessary if the cross - section is uniform), break lines can be used to show that only a part of the shaft is represented.

Answer:

only part of an object is represented to save space
