The class automatically assigned to a plug-in object can be changed through the Standard Naming dialog box.
1) Select File > Setup > Standard Naming.
2) Display the setup names for classes.
3) Select the reference naming standard and then select a custom active standard for the file.
4) Scroll to the class name to be changed and type the desired name in the Edit Class Name field and click OK.
All instances of that class name are updated to the new name.
