Enumeration
An Enumeration definition is a kind of an Attribute definition defining a set of enumerated values. To use enumerations, define an Attribute usage that is feature-typed by an Enumeration Definition
Creating an Enumeration definition
To create an Enumeration definition from the System Structure Diagram toolbar:
1. On the System Structure Diagram toolbar, click the Enumeration definition button.
2. Click on the diagram canvas to the create the item.
3. To use it with an attribute, click the Feature Typing button, then click on the edge of the Attribute Usage item and then click on the Enumeration Definition that you just created.
To create an Enumeration definition or Usage from the context menu in a Package browser:
• Right-click on the element for which you want to create the Enumeration Definition, and select New > SysML2 > Structure Definition > Enumeration Definition or
• Right-click on the Enumeration Definition for which you want to create the Enumeration Usage, and select New > SysML2 > Structure > Enumeration.
* 
You cannot create an Enumeration Usage item directly onto the diagram canvas. You can only scope it within an Enumeration Definition.
