natural reaction as we directly think of rotation as spinning 
about the center of objects such as wheels. 

To recreate this effect in Modeler, the explicit modelers 
would determlne the boundaries of an object, calculate its 
center, then rotate the object with Modeler's numeric Rotate 
tool. But. again. calculation is unnatural. In real life we 
don't calculate the center of our bodies In order to turn 
around and, because of this, we will never actually rotate 
about the true center of our body. 

Likewise, an impllclt modeler would probably never rotate an 
object about its true center using the interactive rotation 
tool. Distance 8 Angles found in MacroForm's 
ProductlvltyToolz allows us to use our natural way of 
thinking about rotation while using pinpoint accuracy, 

Exercise #3: Rotate Demo 
 
1.activate the Tutorialz (F1) or (F11 ) tool 
  the Tutorialz requester will appear 

2.Select Rotate DemO and click OK or hit Return 
   the tutorialz requester will disappear and an object wlll be 
   loaded into Modeler 

This object is resting at a 45 degree angle in the face view. 
What if we wanted to rotate this obJect about its center 45 
degrees to get it straight? Distance ~r Angles will allow you 
to rotate an object arbitrarily about its center: 

3. activate Distance a Angfes (F4) 
   the Distance a Angles requester will appear 


Since Distance a Angle defaults to rotation about the center 
of an obJect. you won't have to change any of the Reference 
Axis settings. The thing we must do is enter our desired 
degree of rotation. You'll notice that there are 3 fields at the 
bottom of the requester. It is here that you will enter your 
degree of rotation. In other modes these Welds have a 
special purpose, but typically only one field is active at a 
tlme. Each corresponds to a rotation in a particular view. 
You select whlch view will be atfected by selecting the 
buttons just above the rotation fields. In this case we want 
to perform a rotation in the face vlew so we need to select 
the FACE button: 

4. select the Rotate-FACE bufton 
    to rotate the object in the face view
