L-TYPE allows you to change the line type (or style) of
entities and witness lines.

You can use the L-TYPE: parameter in the Status Window, or
the Immediate Mode command, ALT-T, to set the current line
type.

Choose one of the following options:

CURRENT - to set the existing modal attribute value in
          effect. All entities created from this point on 
          take on the new attributes for line type 
          assigned.

CHANGE  - to define new line type attribute values only to
          selected existing entities. This does not alter 
          the current values assigned to the attribute in 
          the Status Window.
