WIT/LDR (witness/leader) allows you to control the display
of witness lines and leader lines for newly-created
dimensions.

WITNESS and LEADER options apply to all dimensions you
create until you select different options.

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

Access LEADER from anywhere in the program by cursor
selecting LDR: from the Status Window.

In linear dimensioning, CADKEY defines the first witness
and leader line from the first reference point you select.
 
In angular dimensioning, CADKEY defines the first witness
and leader line from the first line you or endpoint you
select.

Choose an option from the WIT/LDR menu:

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

LEADER  - to control the display of leader lines in linear
          and angular dimensions.
