About Defining 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.

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 or PLAN to define paper space views. The view in paper space is always a plan view. Use the PERSPECTIVE system variable to turn off perspective views in drawings created in AutoCAD.
