You can create a new value or object through the shortcut menu Add Value of a property typed by a primitive type, a Class, or a block in the Variables pane. The shortcut menu will be available only when the number of existing values or objects of the selected property is less than the upper multiplicity of the property.

If a property is typed by a primitive type (and SysML primitive value types), Cameo Simulation Toolkit will add a new value, which is a default value of the primitive type, as the value of that property. 

If a property is typed by a class or a Block, Cameo Simulation Toolkit will show a list of Classes or Blocks containing the Class or the Block that types the property and all of its subtypes, which are not abstract Classes or abstract Blocks. When you select a Class or a Block from the list, Cameo Simulation Toolkit will initialize an object from that Class or Block and set the object as the value of the property.
