Viewing objects in shaded mode
 
                
               
             
             
            
            Workflow overview
          
       
       
       
       
      The columns are made up of multiple primitives
         that are moved, scaled, and rotated into position. Once the first
         column is created, with each component named and accurately positioned,
         you will group and duplicate it to create others.
      
      To
         create a polygonal cube for the pedestal
      
      
         - From the Main Menu, select 
                     Create > Polygon Primitives > Cube >  . .
- In
            the Polygon Cube Options window,
            select Edit > Reset Settings and then
            set the following options:
            
               - Width:
                  1.75
               
- Height:
                  0.6
               
- Depth:
                  1.75
               
 Leave the other options at their default settings.
             NoteIf the  Polygon Cube Options window
                  does not appear, ensure that the  Interactive Creation option
                  for primitives is turned off by first selecting  Create > Polygon Primitives > Interactive Creation so
                  that a check mark does not appear beside this menu item.
                
 
- In
            the Polygon Cube Options window,
            click Create.
            Maya creates a cube primitive and positions
               it at the origin.
             
- In
            the side view, move the cube upwards (Y axis) so it rests on the
            top surface of the temple base.
            You can do this using the Move
                  Tool or with the Channel Box.
               If you use the Channel Box, enter a Translate
                  Y value of 2.3.
             You may find it useful to dolly or tumble the
               scene view to obtain a better viewpoint.
             
- In
            the Channel Box, rename the cube columnPedestal.
         
To
         create a polygonal cylinder for the shaft
      
      
         - From
            the main menu, select 
                     Create > Polygon Primitives > Cylinder >  . .
- In
            the Polygon Cylinder Options window,
            select Edit > Reset Settings and then
            set the following options:
            
               - Radius:
                  0.5
               
- Height:
                  6
               
- Axis
                     divisions: 12
               
 Leave the other options at their default settings
             
- In
            the Polygon Cylinder Options window,
            click Create.
            Maya creates the cylinder primitive at the origin.
             
- In
            side view, move the cylinder upwards (Y axis) so it rests on the
            top surface of columnPedestal.
            You can do this using the Move
                  Tool or with the Channel Box.
               If you use the Channel Box, enter a Translate
                  Y value of 5.6.
             
- In
            the Channel Box, rename the cylinder columnShaft.
         
The capital for the column rests on top of the
         column and is very similar to the pedestal. You duplicate the pedestal
         and position the duplicate at the top of the column.
      
      To
         duplicate the pedestal to create the capital
      
      
         - With
            only columnPedestal selected, select 
                     Edit > Duplicate Special >  from
            the main menu. from
            the main menu.The Duplicate Special Options window
               appears.
             
- In
            the Duplicate Special Options window,
            select Edit > Reset Settings and then
            set the following options:
            
               - Translate:
                  0 6.6 0
               
- Scale:
                  0.8 1.0 0.8
               
 Leave the other options at their default settings.
             
- In
            the Duplicate Special Options window,
            click Duplicate Special.
            Maya creates a duplicate of the columnPedestal
               object and moves and scales it based on the options you set.
             NoteIf you positioned the geometry for the column
                  using the Transform Tools and your mouse, the Y translate values
                  may be incorrect for your particular model. You may want to continue
                  positioning the objects by visual reference using your mouse.
                
Using the duplicate options is an alternate
               method for positioning and scaling duplicated objects when you can
               anticipate its final location.
             
- In
            the Channel Box, rename the duplicated
            cube columnCapital.
The base for the column rests on top of the
         pedestal. You will create the base using one half of a NURBS sphere
         primitive and then move and rotate it into position. You will do
         this by modifying the creation options for the sphere primitive.
      
      To
         create a NURBS sphere for the column base
      
      
         - Select 
                     Create > NURBS Primitives > Sphere >  . .
- In
            the NURBS Sphere Options window,
            select Edit > Reset Settings and then
            set the following options:
            
               - Start
                     Sweep Angle: 0
               
- End
                     Sweep Angle: 180
               
- Radius:
                  0.75
               
- Number
                     of Sections: 8
               
- Number
                     of Spans: 4
               
 Leave the other options at their default settings.
             
- In
            the NURBS Sphere Options window,
            click Create.
            Maya creates a half-sphere primitive at the
               origin. 
             
The sphere needs to be rotated 90 degrees and
         then positioned on top of the pedestal.
      
      To
         rotate and position the sphere on the pedestal
      
      
         - In
            side view, rotate the sphere so that the dome part is pointing up.
            This
               is accomplished by either of the following methods:
             
               - Rotating
                  the sphere about the X axis using the Rotate Tool’s
                  manipulator handle.
               
- Using
                  the Channel Box to change the Rotate
                     X value to -90.
               
 
- Move
            the sphere so it rests on the top surface of columnPedestal (Translate Y
            = 2.6, if you have been inputting values into the Channel
               Box).
         
- Using
            the Scale Tool, scale the sphere
            along its Z axis (blue manipulator handle) so that the sphere becomes
            slightly squashed in appearance.
            When
               you scale an object non-uniformly along one of its axes, you are scaling
               it non-proportionally.
             
- In
            the Channel Box, rename the sphere columnBase.
