 Creates a multi-layer wall arc through three points.

         1. (NUM) option: 0 - free arc, 1 - in one wall, 2 - between two walls
      for option 1:
         2. (IND) wall to create arc in
      for option 2:
         2. (IND) first wall of arc
         3. (Y/N) confirm choice
         4. (IND) second wall of arc (press <ENTER> for a NEW first wall)
         5. (Y/N) confirm choice
      for all options:
         6. (POINT) starting point of arc
         7. (POINT) intermediate point of arc (press <ENTER> for a NEW start
                    pt.)
         8. (POINT) end point of arc (press <ENTER> for a NEW intermediate pt.)
         9. (Y/N) defined points relate to concave arc surface, n-convex <y>




 Description:
 Using this command, you may create free arcs, i.e., not connected to any other
 walls, or an arc within an existing straight multi-layer wall. You may also
 create an arc between two disconnected straight walls.
 State whether the arc is to be a free arc, within a wall or between two
 aligned walls.
 Free arc  concave or convex
 Specify three points (first, intermediate and last). State whether the points
 are to be on the concave or convex surface of the arc.
 Arc within an existing wall or between two walls  CONVEX surface
 For an arc within a wall, indicate the wall in which the arc is to be created.
 For an arc between two walls, indicate the two walls between which the arc is
 to be created.
 Specify three points (first, intermediate and last). Be sure that the first
 and last points are on that side of the wall which will be the CONVEX side of
 the arc. Specify that the points relate to the CONVEX surface of the arc.
 Arc within existing walls or between two walls  CONCAVE surface
 For an arc within a wall, indicate the wall in which the arc is to be created.
 For an arc between two walls, indicate the two walls between which the arc is
 to be created.


 Specify three points (first, intermediate and last). Be sure that the first
 and last points are on that side of the wall which will be the CONCAVE side of
 the arc. Specify that the points relate to the CONCAVE surface of the arc.
 Arc within an existing wall or between two walls  CONCAVE surface - additional
 option
 This option creates an arc whose concave surface passes through the defined
 points but the points are on that side of the wall which will be the convex
 side of the arc.
 For an arc within a wall, indicate the wall in which the arc is to be created.
 For an arc between two walls, indicate the two walls between which the arc is
 to be created.
 Specify three points (first, intermediate and last). Be sure that the first
 and last points are on that side of the wall which will be the CONVEX side of
 the arc. Specify that the points relate to the CONCAVE surface of the arc.
