You can define a parallel projection.
Define Parallel Projections
To determine the point or angle in model space, you can
- 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.
