3DGuy. I am a technical illustrator by training (the old fasioned way, Rotring pens and a 000 brush, more years ago than I care to remember
) and our TI lecturer used to have a saying that I have found useful over the years. TIs are all a bunch of technical perfectionists, especially when it comes to producing things like exploded views of engines and the like... we would spend ages faffing around trying to get the "correct angle" of elipse for the end of a shaft etc. Our lecturer would shake his head and say "
If it looks right, it is right"
I think that this is something that a lot of CG artists seem to forget. It may be an exact reproduction of the object in question, but if it doesn't look quite "right" then, as a finished piece of artwork, its not right. A bit of artistic licence goes a long long way
