Angle of Rotation

A positive angle of rotation is in the direction of the +X-axis to the +Y-axis as shown below.

A negative angle of rotation is in the direction of the +X-axis to the −Y-axis.

Figure 20-4 Drawing arcs (2 of 3)

The relationship of the +X-axis to +Y-axis (and -Y-axis) can change as a result of the scaling point or scaling factor changes, thus, changing the direction of a positive (or negative) angle of rotation.

You can also draw arcs using the Absolute Arc Three Point (AT) and Relative Arc Three Point (RT) commands. These commands use three known points (your current pen location plus two points you specify) to calculate a circle and draw the appropriate arc segment of its circumference. The arc is drawn with a positive angle of rotation, so that it passes through the intermediate point before the end point. Refer to the following illustration.
