# Creating Arc

The following 3 methods can be used to create an arc.

• Specifying the "center point," "through point" or "radius," "start point" and "end point" or "arc length," of an arc.
• Specifying the "center point," "through point" or "radius," "start angle" and "end angle" or "arc length," of an arc.
• Specifying the "center point," "through point" or "radius," "start shape" and "end shape" or "arc length," of an arc.

To display a command parameter to be executed, click / of command parameters, or press Tab key or / key on the keyboard.

1. Point [Arc] on [Shape] menu, and click [Arc].
Then you will be able to create an arc.
2.  Supplemental · You can enter into the arc creating status by clicking on [Shape] toolbar.
3. Click the center point of an arc on the drawing.
4. Specify the radius of an arc.
When specifying the through point
Switch the parameter on Command Window to [Through Point] box, and click the through point of an arc.
A line connecting the center and through points will be a radius of an arc.
When specifying a radius length
Input the length of the radius of the arc in [Radius] box on Command Window.

### When specifying the "start point," "angle" and "end point" of an arc.

1. Switch the parameter on Command Window to [Start Point] box, and click the start point of an arc on the drawing.
2. Switch the parameter on Command Window to [End Point] box, and click the end point of an arc on the drawing.
An arc connecting the start and end points will be created.

### When specifying the start and end angles of an arc

1. Input the start angle for an arc in [Start Angle] box on Command Window.
2. Input the end angle for an arc in [End Angle] box on Command Window.
An arc connecting the start and end angles will be created.

### When selecting the intersection with other shape as the start and end points of an arc

1. Switch the parameter on Command Window to [Start Shape], and click a shape to be used as the start point.
2. Switch the parameter on Command Window to [End Shape] box, and click a shape to be used as the end point.
An arc connecting to the intersection with the selected shape will be created.
 Supplemental · Arcs can also be created by switching the final parameter to [Arc length] box and entering the length of the arc. · You can specify the center, through, start and end points by inputting X and Y coordinates in [Center Point], [Through Point], [Start Point] and [End Point] boxes on Command Window.
