Select properties

You can add or remove user-defined properties from the class.

Show Object Type
Select this check box if you want to display object valued properties.
Selected
The Selected list box contains the names of properties already assigned to this class. To remove a property from the class, select it and click Remove. Note that inherited properties cannot be removed.
Show Inherited
Select this check box to display properties that have been inherited.
Show System
Select this check box to display properties that are owned by the system and therefore unalterable.

To create a property

Click New to launch the Create a Property Template wizard.

NOTE  The order in which the properties appear reflects the order in which they will be saved. If the class has one or more subclasses, you should not try to change the order of the properties by removing them and adding them back to the end of the list. Doing so will only result in error. However, if the class has no subclasses, you can change the order of the properties.
