Question 16

Question 17

Extension lines can be used to show the extension of a surface to a theoretical intersection.

Question 18

Visible lines, also called object lines or outlines, describe the visible surface or edge of the object, and are drawn .2 in. (0.6 mm) wide.

Question 19

The arrowhead is omitted when a leader line points to a dimension line. This is done when there is not enough space for text to be inserted at the dimension line, and the text is connected to the leader.

Question 20

Military (MIL) standards recommend three line thicknesses: thick (cutting and viewing-plane, short break, and object), medium (hidden and phantom), and thin (center, dimension, extension, leader, long break, and section).
