Commands

3DORBIT

Rotates the view in 3D space, but constrained to horizontal and vertical orbit only.

DVIEW

Defines parallel projection or perspective views by using a camera and target.

System Variables

BACKZ

Stores the back clipping plane offset from the target plane for the current viewport, in drawing units.

FRONTZ

Stores the front clipping plane offset from the target plane for the current viewport, in drawing units.

LENSLENGTH

Stores the length of the lens (in millimeters) used in perspective viewing.

PERSPECTIVE

Specifies whether the current viewport displays a perspective view.

PERSPECTIVECLIP

Determines the location of eyepoint clipping.

TARGET

Stores the location (as a UCS coordinate) of the target point for the current viewport.

VIEWDIR

Stores the viewing direction in the current viewport, expressed in UCS coordinates.

VIEWMODE

Stores the View mode for the current viewport.

VIEWTWIST

Stores the view rotation angle for the current viewport measured relative to the WCS.
