Would it be posssible to write a macro that automatically resized the screen model to display at actual size at the press of a button? Obviously, as it would be specific to the monitor the model is being viewed on a user adjustable variable must exist such that the display can be 'calibrated' to display at more or less actual size. I currently view parts full size by zooming while holding a rule to the screen for a known component dimension. It's just that occasionally it is really useful to see a part at real size. Suits my products but admittedly not so much use for someone designing ships! Thanks in advance.
