DESCRIPTION

     These commands control the	setting	and the	use of the  work-
     angle feature.

  wa: WORK-ANGLE TOGGLE
     The wa command toggles the	work-angle mode.   When	 used,	a
     message similar to	one of the following will be displayed on
     the message line to inform	 you  of  the  current	operating
     mode:

	 New work angle:  ON - angle
	 Work Angle mode: OFF

     If	a work-angle has not been previously set, then the  first
     time  this	 command  is issued, the following prompt will be
     displayed:

	 Method	to set angle?  def: angle  angle  line	points

     Select the	desired	method for specifying the work-angle  and
     enter  the	 appropriate information.  See the following dis-
     cussion for information on	how to set the work-angle.

  wan: WORK-ANGLE NEGATIVE
     The wan command toggles the current work angle to its  nega-
     tive  value.   For	 example,  if  the  current angle is 23.6
     degrees, this command would set  the  work	 angle	to  -23.6
     degrees  and vice versa.  This is useful for rapidly switch-
     ing between two  angles  which  are  mirror  images  of  one
     another such as the two planes of a sloping roof.

  waa: SET WORK-ANGLE BY ANGLE
     The waa command allows you	to set a new work-angle	by speci-
     fying a decimal value for the desired angle.  When	used, the
     following prompt is displayed:

	 Work angle?  def: angle  15  30  45  60  90  OTHER

     Use B1 to select one of the displayed values or  else  enter
     the  desired angle.  When finished, a message similar to the
     following will be displayed:

	 New work angle:  ON - angle

  wal: SET WORK-ANGLE BY LINE
     The wal command allows you	to set a new work-angle	by match-
     ing the angle of an existing line.	 When used, the	following
     prompt is displayed:

	 Line for angle	selection:

     Use B1 to select an existing line displayed on  the  screen.
     Selecting	near  the  end	of  the	 line will set the X-axis
     pointing towards the other	end of the line.  When	finished,
     a message similar to the following	will be	displayed:

	 New work angle:  ON - angle

  wap: SET WORK-ANGLE BY POINTS
     The wap command allows you	to set a new work-angle	by  indi-
     cating  two  existing  points.   When  used,  the	following
     prompts are displayed:

	 First point:
	 Second	point:

     Use B1 to	select	two  existing  points  displayed  on  the
     screen.   When  finished, a message similar to the	following
     will be displayed:

	 New work angle:  ON - angle

  wab, waba: SET WORK-ANGLE BY BISECTING ANGLE
     The wab and waba commands allows you to set a new work-angle
     by	 specifying three points used to define	an angle which is
     then bisected to determine	the new	work angle.   When  used,
     the following prompts are displayed:

	 Enter 1st angle leg point (<CR>:exit):
	 Enter angle vertex point (<CR>:exit):
	 Enter 2nd angle leg point (<CR>:exit):

     Specify the three	points	which  define  the  angle  to  be
     bisected.	When finished, a message similar to the	following
     will be displayed:

	 New work angle: angle

     If	the waba command is used, the resulting	angle will be any
     positive  value  between  0 and 360 degrees as determined by
     the specified points.

     If	the wab	command	is used, then the resulting angle will be
     adjusted  so  that	 either	 the  X	or the Y-axis bisects the
     specified angle and the cursor's  positive	 X-axis	 will  be
     automatically  oriented  to  be  within  45-degrees of zero.
     (i.e., between -45	and +45	degrees).  This	is useful if  you
     wish to maintain a	cursor orientation that	does not flip too
     far from normal.

  wa#: SET WORK-ANGLE BY VALUE
     The commands wa0, wa5, wa10, wa15,	wa30, wa45,  wa60,  wa75,
     wa90,  wa135  and	wa180 are shorthand notations for quickly
     setting the work angle  to	 these	typical	 specified  angle
     values.
