The points (13,23,33) and (14,24,34) specify the endpoints of the line used to determine the first extension line. Points (10,20,30) and (15,25,35) specify the endpoints of the line used to determine the second extension line. Point (16,26,36) specifies the location of the dimension line arc. The point (11,21,31) specifies the midpoint of the dimension text.

The point (15,25,35) specifies the vertex of the angle. The points (13,23,33) and (14,24,34) specify the endpoints of the extension lines. The point (10,20,30) specifies the location of the dimension line arc and the point (11,21,31) specifies the midpoint of the dimension text.
