Dimension menu: Angular
Command line: dimangular
Select Arc Selection, Circle Selection, Line Selection, or <Three-Point Specification>:
Select an arc, circle, or line, or press ENTER to create the angular dimension by
specifying three points
After you define the angle to dimension, the following prompt is displayed:
Specify Dimension Arc Line Location or [Mtext/Text/Angle]:
Arc Selection
Uses points on the selected arc as the defining points for a three-point angular
dimension. The center of the arc is the angle vertex. The arc endpoints become
the origin points of the extension lines.
angle vertex
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.
Specify second angle endpoint: Specify a point (2)
The second angle endpoint is the origin of the second extension line and does
not have to lie on the circle.
