Cone of vision
-
what is the optimum cone angle of vision when we set zoom views? is 35 degrees right?

It is a matter of preference - like the lens you choose when you take photographs. 35 degrees is equivalent to a short telephoto or a "portrait" lens, and if you prefer a more wideangle effect you can choose something at about 60 degrees. In SketchUp the angle is measured vertically, so on a normal horizontal monitor, the appearance is always somewhat more wideangled than in a standard camera lens, where the angle is measured diagonally across the picture frame.
