Create arcs

This tool allows you to create an arc by specifying two or three endpoints and then manipulating the center point/radius.

To create a two-point arc

1. Select Create > Curve Tools > Two Point Circular Arc.
2. Click to place the first endpoint, an on-curve point, and the second endpoint of the arc.

   Maya shows a manipulator for the new arc.

3. Do any of the following:
   • Drag any of the points to move them.
   • Press Enter to finish the arc.

To create a three-point arc

1. Select Create > Curve Tools > Three Point Circular Arc.
2. Click to place the three endpoints of the arc.

   Maya shows a manipulator for the new arc.

3. Do any of the following:
   • Drag the endpoints or center point to move them.
   • Click the circle to switch the direction the arc travels between endpoints.
   • Press Enter to finish the arc.

Edit an arc after creation

1. In the channel box, select the CircularArc node associated with the arc you want to change.
2. In the toolbox, click the Show Manipulator tool.

   The arc manipulator will appear.

Notes

• You cannot create a complete circle with the Arc tools. Instead, select Create > NURBS Primitives > Circle.
• Points in the arc cannot have the exact same position.
