Modifying the view cone graphically is a quick way to set up a view for rendering. However, for more precise manipulation, you can select from the camera action icons available in the Define Camera tool's icon bar. These let you quickly and precisely adjust a view with controlled movement of the view cone. This can be:

• Relative to the pointer movement in the camera view.
• With Controlled Movement, such that each data point moves, revolves, or rotates the view cone by a defined distance or angle.
• As defined by key-ins in the relative settings fields.
