5 Using 3D Guidance in theField
Note – For more information on using the Select 3D Guidance Line dialog, see
Selecting a 3D line, page 119.

Horizontal Alignment dialog:
Use the arrow keys to move the cross-hairs around the screen.
To zoom the current view in and out, press + or -.

press Zoom Target.
