Question

Quizplus · Accepted Answer

Extension lines are commonly used in technical drawings to indicate the extension of a surface to a theoretical intersection or to indicate the dimensions of a feature. They are thin lines that extend from the object and are drawn perpendicular to the surface being extended. The purpose of extension lines is to provide clarity and ensure that the drawing is accurately interpreted by the person reading it. Therefore, the statement that extension lines can be used to show the extension of a surface to a theoretical intersection is true.
