The dimension line is drawn as an arc between the extension lines. The
extension lines are drawn from the angle endpoints to the intersection of the
dimension line.
Circle Selection Uses the selection point (1) as the origin of the first extension
line. The center of the circle is the angle vertex.
The second angle endpoint is the origin of the second extension line and does
not have to lie on the circle.
Line Selection Defines the angle using two lines.
The program determines the angle by using each line as a vector for the angle
and the intersection of the lines for the angle vertex. The dimension line spans
the angle between the two lines. If the dimension line does not intersect the
lines being dimensioned, extension lines are added as needed to extend one
or both lines. The arc is always less than 180 degrees.
Three-Point Specification Creates a dimension based on three points you
specify.
The angle vertex can be the same as one of the angle endpoints. If you need
extension lines, the endpoints are used as origin points.
