WITNESS allows you to specify which of the two witness
lines is displayed for newly-created dimensions.

Use WITNESS from anywhere in the program by cursor
selecting WIT: from the Status Window, or by using the
Immediate Mode command, (Ctrl)-(B). 

In linear dimensioning, CADKEY defines the first witness
line from the first reference point you select. 

In angular dimensioning, CADKEY defines the first witness
line from the first line you or endpoint you select.

Indicate the method of displaying witness lines by 
choosing from the following options:

BOTH   - to display both witness lines.

FIRST  - to display only the witness line for the first
         dimension point.

SECOND - to display only the witness line for the second
         dimension point.

NONE   - to display no witness lines.
