Use this command to add an interior angle to any two lines using the current Dimension Settings of the drawing.
The two lines must share a common end point, forming the vertex of the interior angle. You must also select the lines so that the end of the interior angle is clock-wise from its beginning.
The end caps of the inserted angle can be set to an arrow or a slash in the Dimension Settings dialog.
