Define a Parallel Projection

You can define a parallel projection.

To determine the point or angle in model space, you can

Choose a preset 3D view from the View toolbar.
Enter a coordinate or angles that represent your viewing location in 3D.
Change to a view of the XY plane of the current UCS, a saved UCS, or the WCS.
Change the 3D view dynamically with your pointing device.
Set front and back clipping planes to limit the objects being displayed.

Viewing in 3D is available only in model space. If you are working in paper space, you cannot use 3D viewing commands such as VPOINT, DVIEW, or PLAN to define paper space views. The view in paper space is always a plan view.

Procedure

To create a parallel projection dynamically

At the Command prompt, enter dview.
Do one of the following:
- Select the objects to display and press Enter.
- Press Enter without selecting objects to see a representation of a house that shows the current viewing angle.
Enter ca (Camera).
By default, a camera point is set at the center of the drawing.
Adjust the view as if you're aiming a camera.
You can set your view dynamically by moving the crosshairs and clicking.
To switch between the angle-input methods, enter t (Toggle Angle).
You can also adjust the view with one of two angle-input methods.
- For the Enter Angle from the XY Plane option, enter the angle of the camera up or down relative to the XY plane of the current UCS. The default setting, 90 degrees, points the camera straight down from above.
  After you enter the angle, the camera is locked at that height, and you can rotate the camera about the target with the rotation angle measured relative to the X axis of the current UCS.
- For the Enter Angle in the XY Plane from the X Axis option, rotate the camera about the target with the rotation angle measured relative to the X axis of the current UCS.
When you finish specifying the parallel projection, press Enter.
