Select the Isoparametric Machining icon
        
.
        
        An Isoparametric Machining entity along with a default tool 
        is added to the program. 
        The Isoparametric Machining dialog box appears directly at 
        the Geometry tab page
        
.  
        The part surface and corner points of the sensitive icon are colored red 
        indicating that this geometry is required. 
        All other geometry is optional.

Click the red part surface in the icon then select the 
        desired surfaces in the 3D window.
        The Face Selection toolbar appears to help you select faces 
        or belts of faces. 
        These can be adjacent or non-adjacent. For more information please refer 
        to Non-Adjacent Belts of 
        Faces.

Click a red point in the icon then select the four 
        corner points of the selected surfaces.
        Machining starts from point 1 to point 2, and finishes either from point 
        3 to 4 or 4 to 3 
        (depending on the One way or Zig zag tool path 
        style).
        The part surface and corner points of the icon are now colored green 
        indicating that this geometry is now defined.

             | 
          
          
            
            
              A default reference tool axis (A) and 4-Axis 
              Constraint arrow (N) are displayed.  
              You can double click these axes to modify them. 
                
                
             
             | 
          
          
            
            
              Click the 4-Axis Constraint arrow (N).  
              This is the normal to the plane in which the tool axis is 
              constrained.   
              A dialog box appears 
              showing the default direction. You can modify this direction, if 
              needed.

A tool is proposed by default when you want to create a 
        machining operation. 
        If the proposed tool is not suitable, just select the 
        Tool tab page
        
 
        to specify the tool you want to use.  
        Please refer to
        Edit the 
        Tool of an Operation.

Select the Feeds and Speeds 
        tab page 
 to 
        specify the
        
        feedrates and spindle speeds for the operation.
 
        - 
        
Select the Macros tab 
        page 
 to 
        specify the operation's transition paths (approach and retract motion, 
        for example).
        See Define 
        Macros of an Operation for an example of specifying transition paths 
        on a multi-axis machining operation.

Before accepting the operation, you should check its 
        validity by 
        replaying the tool path.
