Hi Geoffrey, I think you are a bit harsh about Technic/NXT building with LDD. I agree with you that it is not perfect, and it is sometime painful to do what you want, but it is possible to virtually build things with it. And the hinge tool does work (...)

This is possible to do, yes you will receive annoying messages that you won't be able to save or upload any models you create, but at least you can wander around in a daze trying to make something using the 'free build' option.
