Hi andras, check out this recent thread:

There is a script in there that you can put on a keyboard shortcut that will send a high resolution screen capture of MoI's viewport display into the clipboard, so you can paste it into an imaging application.

Does that maybe do what you want?

At the moment there isn't any way to turn off the shading, but I do plan on adding in some different shading styles and a "hidden line" style shade can be one of those when I get a chance to work on that area.
