Printing activity diagrams added to use cases

[MrFantastic]

I have different use cases in my project. Each use case has an activity diagram added to explain the use case.

I have tried to make a template to print those activity diagrams adapting "use case template" but I haven`t found any way to include diagrams added to elements of a package.

Does anybody know how to print those activity diagrams with RTF Document Generator?

Thanks.
