Hit the spacebar, this is a shortcut to display four views and this displays the Hot Box, if you hit the spacebar again it will display one view, the view the mouse was last over.


Make sure the select by object type button   sobject.jpg is selected in the status line near the top. This lets you pick objects, rather than points etc.


Choose Create->Polygon Primitives->Cube  A cube will appear at the origin.


Select the Move Tool button from the  the tool box on the left. mmove.jpg  If your cube is still active, a manipulator icon will appear, click and drag on the green arrow to move the cube up approximately 4 units in the Y axis.


Select the Scale Tool button from the side tool box.  mscale.jpg     If your cube is still active a manipulator icon will appear, use this to change the size of the cube or use the channel box on the right side of the screen and input: 
     ScaleX   8
     ScaleY  .5
     ScaleZ   8
If you do not see the channel box, hit the channel button upper right side of the screen.



Legs
Click the front view in order to make the view active,
Hit 4 on the keyboard to switch to wireframe instead of shaded.

Choose Create->NURBS Primitives->Cylinder


Select the Move Tool button from the side tool box. mmove.jpg    Use this to move the cylinder or use the channel box on the right side of the screen and input: 
     Translate X   -3 
     Translate Y    3 
     Translate Z    3

Turn off the preference for the orientation Handle:
     Select Windows->Setting/Preferences->Preferences
     Select the Manipulators section
     Uncheck Orientation Handle
This option gets in the way of the Pivot Handle. The orientation Handle is good for rotating the pivot center. You will not need to do this very often.

Set the pivot center:

Select the cylinder and select the Scale Tool button from the side tool box. mscale.jpg    Hold down the d key, this will switch over to change pivot mode. (You can also use the Insert key on the PC or use the Home key on a mac to toggle (not on a laptop)).

Click and drag on the manipulator's green line to move the pivot up in the Y axis to the upper edge of the cylinder.


Hit the d key until you see the scale manipulator is back. Click and drag on the square  in the middle of the manipulator icon, this will scale down the entire cylinder in three axes.

Click and drag on the top square on the manipulator icon to scale the cylinder in Y. Notice it is scaling around the pivot point you changed.
