Draw Arcs by Specifying Start, End, Direction
You can create an arc using a start point, endpoint, and a tangent direction
at the start point.
The tangent direction can be specified either by locating a point on the desired
tangent line, or by entering an angle. You can determine which endpoint
controls the tangent by changing the order in which you specify the two
endpoints.
Draw Arcs by Specifying Start, End, Radius
You can create an arc using a start point, endpoint, and a radius.
The direction of the bulge of the arc is determined by the order in which you
specify its endpoints. You can specify the radius either by entering it or by
specifying a point at the desired radius distance.
Draw Contiguous Tangent Arcs and Lines
Immediately after you create an arc, you can start a line that is tangent to the
arc at an endpoint by starting the LINE command and pressing Enter at the
Specify First Point prompt. You need to specify only the line length.
Immediately after you create a line or an arc, you can start an arc that is
tangent at an endpoint by starting the ARC command and pressing Enter at
the Specify Start Point prompt. You need to specify only the endpoint of the
new arc.
