Drawing arcs
An arc is a portion of a circle. The default method for drawing an arc is to specify three points--the start point, a second point, and the endpoint. You can draw arcs using any of the following methods:
Three points on an arc (
).- Start point-center-endpoint (
), or Start point-endpoint-center
(
), or Center-start point-endpoint
(
).- Start point-center-included angle (
), or Start point-included angle-center
(
), or Center-start point-included angle
(
). - Start point-center-chord length (
), or Center-start point-chord length
(
). - Start point-endpoint-radius (
), or Start point-radius-endpoint
(
). - Start point-endpoint-included angle (
), or Start point-included angle-endpoint
(
).- Start point-endpoint-starting direction (
), or Start point-starting direction-endpoint
(
).- Start point-radius-angle (
).As a tangent continuation of the previous arc or line
(
).
To draw an arc by specifying three points
- Do one of the following:
- Choose Draw > Arc > 3 Points.
- On the Draw toolbar, click the 3-Point Arc tool (
).- Type arc and then press Enter.
