Click Keyhole Profile 
       
 in the Profile  toolbar 
       (Predefined Profile 
       sub-toolbar). 
 
       The Sketch tools toolbar now displays values for defining the keyhole profile. 
 
Position the stating point at H=20mm, 
       V=20mm
 
Position the small radius center point at H=20mm,
       V=40mm
 
Click to define the small radius.
 
       
         
           
			

         
       
       
 
Click to define the large radius.
 
       
         
           
			

         
       
       
 
       The resulting keyhole is as shown here.
       
         
           
			

Note:
		In this task, we used the Sketch tools toolbar but you can create this keyhole manually. For this, move the cursor 
     to activate SmartPick and click as soon as 
     you get what you wish.
