		 TopSolid'Split 
		 recognizes automatically the Opening 
		 frame previously defined. However, you can choose another 
		 one, or if it doesn't exist, create it "from scratch" 
		  . 
		 If you need it, Reverse

				Automatic: 
				 According the selected Mold 
				 frame, the Shape 
				 to Split topology, TopSolid'Split 
				 detects automatically the direction to use for the extension 
				 of your Guide 
				 edges.  
				Manual: 
				 You indicate the molding axis for the Extension 
				 creation. If it is needed, create it "from scratch" 
				   . 
				 If you need it, Reverse 
				 it  .  
			  
		 
		  
		
		  
		Choose the Limit 
		 of your future Extension 
		 (it means choose the element that will determinate you surface 
		 length): 
		
			
				Length: 
				  Set the surface length.  
				Point: You 
				 select a  that will be the "end" 
				 your Parting Surface. If this point doesn't exist, create

				Stock plane:The 
				 software will "end" 
				 for you the Parting Surface 
				 on the Design 
				 external planes of your Stock.  
				Plane: You 
				 select a  that will "end"

		You can manage the Start

				TopSolid'Split analyses 
				 the edge path, the part topology at its extremities, the 
				 Mold frame and 
				 "find" the automatic extension direction.

				TopSolid'Split extends 
				 the edge path previously selected to trim the Planar 
				 surface:
