Except for the profile Structural Material parameter and the Coating parameter available only for standard connection sub-elements, none of the other instance parameters are editable. 
	 
 About the Steel Profile Sub-Element
 
		 
		- The steel profile sub-element is a beam type element created and controlled by a structural steel connection. 
		  
-  When structural framing is added to a custom connection, it automatically becomes a profile sub-element. 
		  
- When the 
			 connection is broken, the profile element is transformed into a structural framing element with steel fabrication shape, with a new structural framing family and type, created based on the geometrical characteristics of the profile sub-element and it can have different shapes and types. These shapes and types are automatically loaded from the Steel Connections databases and they are not based on Families and Types. 
		  
- Profile sub-elements cannot be changed or edited. The only instance parameter you can change for the profile sub-element is the Structural Material.
