Created with trial Visual Paradigm version.
It miss AIFactory as it couldn't parse it ( c++11 ? ) .
Use Umbrello or other UML modeler. ( You must somehow drag and drop every class onto >>Scatchy<< panel to the right >_> , those are pros and cons of OS's software .... ) .
Argouml won't import that XMI file.

Wanted to create an image file first , but those come huge unhandy ( > 10 MB) files !!!! Trial version makes harder exporting this as compact image files.
