Perspective Projection Settings

Use the View > 3D View Options > 3D Projection Settings command or the 3D Visualization toolbar’s button to open this dialog box.
The angle defining the View Cone is displayed in the preview area and provides reliable information if the line of vision is horizontal. If the line of vision is looking up or down, the angle can be used only for estimating the resulting view.
Camera Z: Enter a value here to specify Camera height from Project Zero. (In this case, the position of the target will remain unchanged.)
Target Z: Enter a value here to specify Target height from Project Zero.
Distance: Enter a value here to specify the horizontal distance between Camera and Target.
Azimuth: Enter a value here to specify Camera Azimuth to Target.
Use Two-Point Perspective: Check this box to view the 3D model from a two-point rather than three-point perspective, while maintaining the original position and viewing angle. This perspective remains until you navigate away.
The elevation of the viewpoint and the target point, as well as the View Cone and Roll Angle of the Camera must be set numerically by using the remaining edit boxes.
View Cone: Enter a value here to specify the opening angle of the Camera View Cone.
Hint: Wider angles (a°=>60°) can fit more objects in the Window, but can also distort the image.
Roll Angle: Enter a value here to specify Camera Roll Angle.
Sun Altitude: Enter a value here to specify Sun Altitude used in shaded or rendered images.
Sun Azimuth: Enter a value here to specify Sun Azimuth used in shaded or rendered images.
Note: Cameras placed in the Floor Plan window also define perspective views, but they are configured in the Camera Tool Settings dialog box, not in this dialog box. You can copy a camera’s settings here by selecting a single camera on the Floor Plan and choosing 3D Projection Settings.
More Sun button: Click here to open a dialog to specify Sun settings.
You can also use the Navigator and Navigator Preview palettes to set up the 3D view.
