It is possible to create arcs in several ways. With the exception of the first method, arcs are drawn counterclockwise from the starting point to the endpoint.
You can draw an arc by specifying three points: the starting, center and end points.
When the starting point, center point and endpoint are known, it is possible to draw an arc by specifying at first either the starting point or the center point. The center point is the center of a circle of which the arc is part.
When having a starting point and a center point to snap to and the included angle is known, it is possible to use the Start, Center, Angle or the Center, Start, Angle option.
The inscribed angle determines the endpoint of the arc. Use the Start, End, Angle method when both endpoints are known but it is not possible to snap to a center point.
When knowing a starting point and a center point (which are possible to snap to) and also the chord length, use the Start, Center, Length or the Center, Start, Length option.
The length of the chord of the arc determines the included angle.
When a starting point and an endpoint are known, use the Start, End, Direction or the Start, End, Radius option.
After having completed an arc, it is possible to start a tangent or perpendicular to the arc at an endpoint, using the Smart polar Snap or the endpoint Snap.
Conversely, after completing a line, it is possible to start an arc tangent to the line at an endpoint by entering the ARC_CON command. It is only necessary to specify the endpoint of the arc.
It is possible to connect sequentially drawn arcs in the same way. To create connected arcs using a menu, click Arc from the Draw menu, and then click Continue. In both cases, the resulting object is tangent to the previous one.
