Step6: To create a new ObjectAid UML diagram, launch the ObjectAid wizard by going to File->new->other.
Type Class Diagram in the top textbox to filter this wizard out. Once you see the right wizard, select it and click 'next'.

Step8 : Once you are done, you can choose to save it as an image. for this, all you have to do is right click on the diagram and choose save as image followed by the specific image type you want to save it as (.jpeg or .gif etc.)
