1.8 VPOINT Command (Tripod) Displays a compass and tripod for defining a view rotation. The compass

represents a two dimensional globe.

1. Choose View, 3D Views, Viewpoint

or

2. Type VPOINT at the command prompt.

Command: VPOINT

Rotate/<Viewpoint><-0.614,-0.614,0.500>: PRESS ENTER

3. Click a point on the compass to define the viewing

angle.

Point in the center of the

compass is the “ north pole”, looking straight down at the

drawing

Middle ring of the

compass is the

“equator”, looking

straight on at the

drawing.

Entire outer ring is the

“south pole”, looking

straight up at the

drawing.
