Cone Angle Manipulator

To create a cone angle manipulator:

1. In the Create panel, go to Helpers and choose Manipulators from the drop-down list.

2. Click to turn on Cone Angle.

3. Drag in a viewport, and then release the mouse.

   The cone angle manipulator is created along the negative Z axis of the viewport in which you drag. In other words, its initial position points away from you.

To change the angle of a cone angle manipulator:

1. Turn on Select And Manipulate.

   Tip: If you are still in the Create panel, turn on Select Object before using the manipulator. Otherwise, it is too easy to create a new one.

2. In a viewport, move the mouse over the manipulator.

   The manipulator turns red when the mouse is over it and it is available to be manipulated. Also, a tooltip appears, showing the name of the manipulator and its current value.

3. Drag the base of the cone angle manipulator's cone.

   The Angle value changes as you drag the manipulator. This value can range between 0.0 and 360.0.

To select a cone angle manipulator:

1. Turn on Select Object.

   You can also use Select And Move, Select And Rotate, and the scale options on a cone angle manipulator.

2. Turn off Select And Manipulate.

   If you don't turn off Select And Manipulate, you adjust the manipulator's Angle value without affecting its properties.

3. Adjust the properties of the selected manipulator.

To connect a cone angle manipulator so it controls another object:

1. Select the cone angle manipulator.

   Note: Select And Manipulate must be off before you can select the manipulator.

2. Choose Animation > Wire Parameters > Wire Parameters.

   You can also right-click the manipulator and choose Wire Parameters from the Transform (lower-right) quadrant of the quad menu.

   A pop-up menu appears over the manipulator.

3. In the pop-up menu, choose Object > Angle.

4. Drag to the object you want to manipulate, and click it.

   A pop-up menu appears over the object.

5. In the pop-up menu, choose Object, then the name of the parameter you want to manipulate.

   The Parameter Wiring dialog appears.

6. In the Parameter Wiring dialog, make sure the direction goes from the manipulator to the object (or both directions), and then click Connect.

7. Close the Parameter Wiring dialog.

   Now when you turn on Select And Manipulate and use the manipulator, the object updates under the manipulator's control.
