As you move the cursor before picking the target location, a pyramid-shaped fi eld of view indicates what will be seen in the view. Once you select the target location, the command remains active for you to select an option: Enter an option [?/Name/LOcation/Height/Target/LEns/Clipping/View/eXit]eXit: The list, or ?, option allows you to list the cameras in the drawing. Select this option and type an asterisk (*) to show all of the cameras in the drawing. You can also enter a name or part of a name and an asterisk. For example, entering HOUSE* will list all of the cameras whose name begins with HOUSE, such as HOUSE_SW, HOUSE_SE, and HOUSE_PLAN. The Name option allows you to change the name of the camera as you create it. If you do not rename the camera, it is given a default, sequential name, such as Camera1, Camera2, Camera3, and so on. It is always a good idea to provide meaningful names for cameras. Names such as Living Room_SW, Corner, or Hallway_Looking East leave no doubt as to what the camera shows. If you choose not to rename the camera at this point, it can be renamed later using the Properties palette. The Location option allows you to change the placement of the camera. Enter the option and then specify the new location. You can enter coordinates or pick a location in the drawing. The Height option allows you to change the vertical location of the camera. Enter the option and then enter the height of the camera. The value you enter is the number of units from the current XY plane. If you are placing the camera in a plan view, this option is used to tilt the view up or down from the current XY plane. The Target option allows you to change the placement of the camera target. Enter the option and then specify the new location. You can enter coordinates or pick a loca- tion in the drawing. The Lens option allows you to change the focal length of the camera lens. If you change the lens focal length, you are really changing the fi eld of view, or the area of the drawing that the camera covers. The lower the lens focal length, the wider the fi eld of view angle. The focal length is measured in millimeters. The Clipping option is used to turn the front and back clipping planes on or off. These planes are used to limit what is shown in the camera view. Clipping planes are discussed later in this chapter. The View option is used to change the current view to that shown by the camera. This option has two choices—Yes or No. If you select Yes, the active viewport switches to the camera view and the CAMERA command ends. If you select No, the previous prompt returns. Once you have made all settings, press [Enter] or select the Exit option to end the command. The view (camera) is listed with the other saved views in the drop- down list in the Named Views panel on the Visualize tab of the ribbon and in the View Controls fl yout of the viewport controls. Selecting the view makes it the current view Figure 21-1. A camera is represented by a glyph. When the camera is selected, the field of view (shown in color) and grips are displayed.
