Accidentally removed Design Pattern

I created a new paltform independent UML project in SJSE8. Made a class diagram and did a drag and drop of the Factory Method from the GOF:Creational. I started modifying it and saw that it was modifying the pattern in the design center. Well I then deleted the objects from the class diagram. That removed the pattern from the design center. Any ideas on how to recover the pattern? I tried an update but that did not work.

Thanks for any help.
