buftons, Distance a Angles will only use the rotatlon field 
corresponding to that view of rotation. Let's continue... 

16. enter 90 minus the value you wrote down in step I O, 
    in the field corresponding to the top vlew rotation (the 
    second Weld) 
        for instance if the value was 16.5 enter 90-16.5 

Modeler automatically calculates the new value of rotation. 
The last step is to accept the Input... 

17. click OK 
         the object will be rotated 

Now the object is sitting straight on the table; having been 
rotated about its center. This is a fairly straightforward and 
effective method for performing this rotatlon. There is, 
however, another method. 

In the last example we rotated the ruler by a relatlve 
amount; that is, the ruler was at an angle and we had to 
compute a new degree in order to achieve the desired 
amount of rotation. Let's say we wanted to rotate the ruler 
to an exact degree, say 25.75, without having to write down 
or remember values or perform calculations. Distance 8 
Angles provides you with this capability. But for this 
particular example, we'll need to copy the ruler to another 
layer to perform the rotations. 

18. In Polygon selection mode, select the polygons of the 
     entire ruler 
         we want to seled only the ruler 

19.hit the 'x' key on your keyboard or click the Cut 
   butfon on Modelers interface 
       we want to remove the ruler from this layer 

20.select an empty layer 
    this is where we will paste the ruler 

21.hit the 'v' key on your keyboard or click the Paste 
    bufton on Modeler's Interface 
      the ruler will appear 

With the ruler isolated in its own layer. we can now perform 
the rotation. In order to rotate this ruler to our exact (or 
absolute) degree of 25.75, we need to first determine what 
the current angle of the ruler is. We will do this using the 
same technlque that we used before; we will select 2 points 
on the object from the top view . But this time we need to
 select them in a partlculaY order. From the
