- 
        
          Modify the 2D shape in such a way that some constrained generated geometry will be modified or deleted.
        
      
 - 
        
          From the standard area of the action bar, click Update.
        
        
        
          Broken constraints are represented by a red warning-like symbol 

. Valid constraints are also displayed.
          

Notes:
    		- When deleting a use-edge, the constraint created with it is broken.
 - When selecting the geometry and its constraints for copy-paste operations, broken constraints are kept and pasted too. If the entire geometry is not selected, constraints are not copied. 
 - The color used to visualize broken constraints is the color defined for inconsistent elements by selecting Activate geometries' diagnostic check box and clicking Configure in 
				
			 section, under  Elements Analysis.
 - The size used as a reference to display broken constraints is the same as the reference size defined for constraints (2 mm by default) in 
				
			 section, under Constraints Display.
 
 
         
       - 
        Move the pointer
over the broken constraint symbol, to  find out the original type of a broken constraint.
        
        
          The constraint type  is displayed in the status bar.
       - 
        Right-click a broken constraint and select Delete or press the Del key.
        
        
        
          The broken constraint is deleted.
        
       - Optional: Delete some geometry.
The associated constraint is also deleted.
 
    
      
        You have now learn to visualize broken constraints.
