       This task shows how
    to create fill surfaces between a number of boundary segments. 
     | 
  
  
      | 
    
       Open the Fill1.CATPart document. 
     | 
  
  
       | 
    
      
        - 
          
Click the Fill icon  .  
       
      
        The Fill Surface Definition dialog box appears. 
         
      
        - 
          
Select curves or surface edges to form a closed boundary.  
       
     | 
      | 
  
  
     | 
    
      
        You can select a support surface for each curve or edge. In this case continuity will
    be assured between the fill surface and selected support surfaces. 
       
     | 
  
  
     | 
    
      
        - 
          
Use the combo to specify the
    desired continuity type between any selected support surfaces and the fill surface: Point
    or Tangent.  
       
      
        The fill surface is displayed within the boundary.
        
     | 
      | 
  
  
     | 
    
      
        - 
          
You can edit the
    boundary by first selecting an element in the dialog box list then choosing a button to
    either:  
       
     | 
  
  
     | 
    
      
          | Add a new element after or before the selected one |  
          | Remove the selected element |  
          | Replace the selected element by another curve |  
          | Replace the selected support element by another support surface |  
          | Remove the selected support element. |  
       
     | 
  
  
       | 
    
       This point should lie within the area delimited by the
      selected curves. If not, the results may be inconsistent. 
     | 
  
  
     | 
    
      
        - 
          
Click OK to
    create the fill surface.  
       
     | 
  
  
     | 
    The surface (identified as
    Fill.xxx) is added to the specification tree. | 
  
  
     | 
    
        
       
     | 
     
         | 
  
  
     | 
    
       Filling surface with specified supports  | 
    
       Filling surface with passing point (P2 only)  |
