 Quiz question review on the 4, 1, 3 answer and the H A N D tutorial
      from chapter four.  

    *** Putting the Tools to Use: Making a Simple Hand pages 111-116 ***

 1. Why is the only possible answer to the HAND tutorial where you 
    are shown the selected Polygon Cube in the default home PERSP
    view 
         4 for the Width,    How do you know X is the Width?
         1 for the Height,   How do you know Y is the Height?
     and 3 for the Depth?    How do you know Z is the Depth?

    Get a piece of paper out.  Draw an X and a Y axis on it to work in 
                               2D graphics.

    Draw a person.

    Draw a house.

    Draw the Campanile.

    9,999 out of 10,000 people would draw the X-axis horizontally on the
          paper and the Y-axis vertically on the paper or if they
          bought some graph paper with the X and Y axis lines drawn into
          the 2D grid, the Axis would be X as horizontal and
                                         Y as vertical.

    9,999 out of 10,000 people would have the person that is standing
    up or walking with their feet and their head at the same X value
    and their feet having a Y value < their head's Y value.

    Now draw your rendition of a 3D box on the 2D grid.  Or a 3D house.

    How to you indicate the depth dimension? 

    In the MAYA PERSP view with Y-up (North and South)

                            and X going east and west or left and right

                            and Z coming out toward you and going back
                                  away from you,

    it is exactly the same way we try to indicate 3D when we do it on
    a sheet of paper, with perhaps a slant of the X and Y axis somewhat.

    In any case, for MAYA the depth is the Z dimension.

    The Height is the Y dimension.

    The Width is the X dimension.

    Notice in the dialogue box for creating a Polygonal Cube that the
    vertical order of these parameters is:

            Width Divisions               X
           Height Divisions               Y
            Depth Divisions               Z

    (x, y, z) is the order we specify the coordinates of a 3D point...

 2. Wedge Face question.

    Key terms:   Marking menu
                 Faces
                 Edges

         1.    RMB (Right Mouse Button) click on the Polygonal Cube object.

         2.    Select Faces from the Marking Menu.

         3.    Click with the (LMB) on the face that is indicated on the 
                     quiz diagram (with the numbered edges).  It is now
                     the selected face.

               Click to select the face indicated on the quiz snapshot.
                             
         4.    RMB click on the Polygonal Cube Object.

         5.    Select Edges from the Marking Menu.

               You have just switched from Component Mode select Faces
                                        to Component Mode select Edges.

         6.    Shift-click to select the edge, edge #4 on diagram.

      Now everything is set up and prepared for doing the WEDGE FACE

          and the SELECTED FACE will have a rotation of WEDGES coming
                              out of edge #4, as shown on the diagram.

   Absolutely key idea:

               SELECT THE FACE first.

               SELECT THE ONE EDGE second.

          What is the prerequisite for selecting a FACE?

          What is the prerequisite for selecting an EDGE?

               That you be in the right COMPONENT MODE for that
                    particular type of COMPONENT.

           H O C always seems to be the K E Y.    HOC KEY

     The Polygonal components you know at this point in the class are:

                  Faces        Edges      Vertices (Vertex is singular)
                  -----        -----      --------
