 Updates the offset of multi-layer walls and arcs.

         1.   (CHAR) options: i - single mwall, s - selection group, a - all
         2.   (Y/N) options: y-by alignment, n-by order of layers
         3.   (NUM) offset of the wall
      if reply to prompt 1 is `s' or `a':
         4. * (IND) reference wall
      if reply to prompt 1 is `i':
         4. * (IND) wall to be updated
      for all options:
         5. * (Y/N) confirm choice
         6. * (POINT) direction point
         7. * (Y/N) keep the result ?

 Description:
 This command updates the offset of multi-layer walls. The command may be
 executed on a single wall, a selected group of walls or all multi-layer walls
 in a single operation.


 Specify whether the wall is to be offset by axis alignment or by order of
 layers. This is critical when you are executing the command on several walls
 that are not parallel to each other. Each wall may have its axis aligned
 differently (irrespective of the order of layers).
 If you select `by alignment', the wall will move by the specified offset in
 the direction established from the axis of the wall to the indicated direction
 point irrespective of the order of layers.
 If you select `by order of layers', the wall will move by the specified offset
 in the direction established from the first layer of the wall to the indicated
 direction point irrespective of the alignment of the axis.
 Specify the new offset of the wall. If you are moving a single wall, indicate
 the wall and confirm its choice, otherwise indicate a reference wall in order
 to give a direction point relative to that wall. Indicate a direction point.
 All corners, T-junctions and openings will be resolved. The T-junction
 solution applied will be the current default solution. Openings will be moved
 together with the wall. The result is displayed and you are asked if you want
 to keep the result. If you reply `n', your original wall/set of walls will be
 restored.
 You are prompted to indicate another wall to update until you enter another
 command.
 NOTE: This operation does not affect multi-layer wall arcs.
