What is a Fillet Feature?
A fillet is a curved face of a constant or
		variable radius 
		that is tangent to, and that joins, two surfaces. Together, these three 
		surfaces form either an inside corner  
		or an outside corner. 
The curved surface of an outside corner is generally 
		called a 'round' and that of an inside corner is normally referred to as 
		a 'fillet'. 
Edge  fillets are smooth transitional 
		surfaces between two adjacent faces.
Reshaping Corners
The Blend Corners option 
		available from Edge Fillet 
		and Variable Radius Fillet
		  dialog boxes lets you quickly reshape these corners.  
		
Interrupting Fillet Computations
If the fillet definition needs modification, you can 
		interrupt the  feature computation launched after clicking OK. 
		This is possible when the computation requires a few seconds to perform.
If the computation exceeds a certain 
		amount of time, a progress dialog box appears providing. To 
		interrupt the operation, click Cancel. This 
		interrupts the process and displays an Update Diagnosis 
		dialog box enabling you to edit, deactivate, isolate or even delete the 
		feature.
This capability is available for any type of fillet 
		features you create or edit.
Deactivate and Extract Geometry Commands
If you perform a difficult fillet operation, for example resulting in 
		twisted faces, you can use the Deactivate and Extract Geometry 
		commands to solve the difficulties. 
Extract  lets you generate 
		separate elements from the initial geometry, without deleting the geometry.
		
When the app displays an error message that the operation cannot be properly performed, close the message box. A new dialog box appear that lets you deactivate feature and extract its geometry.  
The feature is deactivated and is inaccessible in the tree. A node
		Extracted Geometry (Fillet.x) is also displayed in the tree.
