To Add and Label Class Elements
1. From the Basic section of the Modeling Palette, select the Class icon and click once in the Diagram editor. This action places a Class element on the diagram.
2. Deselect the icon by right-clicking anywhere in the Diagram Editor. Note: Each time that you select an icon, you can place multiple instances of that element in the Diagram editor by clicking more than once.
3. If not already selected, select the newly added Class element by clicking it once.
4. Type EntryStation and press Enter. The IDE does the following:
o Labels the Class element with the name EntryStation
o Creates a public operation named EntryStation()
o Displays the Class properties in the Properties window
o Adds a Class element with the name EntryStation under the Model node in the Projects window
