: arc

Prompts you in the command bar:

The first time a drawing command is used in a drawing, you are prompted in the command bar:

Center/<Start of arc>: (Pick a point, enter coordinates, or enter an option.)

Angle/Center/Direction/End/Radius/<Second point>: (Pick a point, enter coordinates, or enter an option.)

End point: (Pick a point or enter coordinates.)

Subsequent uses of this command change the initial prompt to:

ENTER to use last point/Center/Follow/<Start of arc>: (Pick a point, enter coordinates, or enter an option.)

This command draws arcs by 17 methods. You can see the full list in the Draw | Arc menu:

and the Arcs toolbar:

Command Options

Option	Description
ENTER to use last point	Continues the arc tangent from the last point picked.
Center	Specifies the center point of the arc.
Follow	Continues the arc tangent from the last point picked (same as pressing Enter).
Start of arc	Specifies a different start point for the new arc.
Angle	Specifies the included angle, the angle between the arc's start point and: Endpoint. Center point.
Center	Specifies the center point of the arc; after this, you can specify one of the following to complete the arc: Endpoint. Included angle. Length of the chord.
Direction	Specifies the direction of the tangent to the arc's start point; following this, you specify the following: End point.
End	Specifies the arc's end point; following this, you can specify the following: Center point. Included angle. Direction of tangency. Radius.
Radius	Specifies the arc's radius; following this, you can specify the following: Endpoint. Included angle.
Second point	Specifies a point along the arc's circumference; following this, you specify the following: Endpoint.

Procedures

Grips Editing

Arcs can be edited directly through grips:

Select the arc. Notice that it has four grips.
Drag the grips to perform the following actions:
- Drag the endpoint and midpoint grips to stretch the arc.
- Drag the center grip to move the arc.
