Right, but what would you then do with your model in MoI that had lines styles and hatching just only visible on the screen, just look at it and nothing else?

Probably there are various other feature areas that go along with that, like generating image output and printing, are you really sure that simply changing the line style only inside the viewport alone would really get you what you need?

The next step for this area I think will be making it easier to generate a hidden-line vector drawing which will then make it easier to use MoI in combination with a 2D program for doing the styles and hatching. At some point I do want to have all that stuff included directly in MoI itself at least at a basic level but I think that it's a much larger amount of work and involves several intertwined features to a bigger level than what you may really be thinking...
