Draw Curved Objects
Curved objects are arcs, circles, polyline arcs, donuts, ellipses, and splines.
Draw Arcs
To create an arc, you can specify various combinations of center, endpoint,
start point, radius, angle, chord length, and direction values.
You can create arcs in several ways. With the exception of the first method,
arcs are drawn counterclockwise from the start point to the endpoint.
Draw Arcs by Specifying Three Points
You can create an arc by specifying three points. In the following example,
the start point of the arc snaps to the endpoint of a line. The second point of
the arc snaps to the middle circle in the illustration.
Draw Arcs by Specifying Start, Center, End
You can create an arc using a start point, center, and a third point that
determines the endpoint.
The distance between the start point and the center determines the radius.
The endpoint is determined by a line from the center that passes through the
third point. The resulting arc is always created counterclockwise from the start
point.
Using different options, you can specify either the start point first or the center
point first.
