model to a specific size you had to first figure out the 
appropriate scaling factors before you used the slzing or 
stretching tools. With Dimensions these methods are a thing 
of the past. When you activate Dimensions (F3) a requester 
appears that returns the physical size of the data in the 
current layer. It also allows you to change that size just by 
typing in an absolute value. Let's try this next example: 

Exlercise #2 : Dim ensions Demo 

1.activate the Yutorialz (F1/FI I ) tool 
  the Tutorialz requester will appear 

2.select the button labeled Dimensions Demo and cllck 
  OK or hit Return 
   objects will appear in layers 1, 2, and 3 

3.activate Dimensions (F3) 
   the Dimensions requester will appear 

The numbers returned in the Data Size area are the actual 
physical dimensions of the sphere object in the current layer. 
As you can see, the sphere is squashed. We will alter its size 
so that it becomes a true sphere.,. 

4. enter1 in the WIDTH..X, I in the HEIGHT..Y, and I in the 
  DEPTH..Z fields and click OK or hit Return 
    the sphere will scale to this new size 

Now the sphere is properly sized. We can check this by 
activating Dimensions (F3) again... 

5.actlvate DimenSions (F3) 
  the Dimensions requester wi[1 appear 

Now look at the Data Size fields. you can see that the sphere 
is a true sphere because all of its dimensions (width, height, 
and depth) hold the same value. 

Choosing a Reference 

When the object scaled, did you notice where it scaled from? 
Since you may have missed this, Iet's look at it again... 

6.click Cancel on the Dimensions requester 
     the Dimensions requester will disappear 
7.click Undo on the Modeler's screen several times 
    while looking at the object 

As you can see from this test, the sphere sized from its 
center, (i.e., the scaiing happened toward or away from the
