Thanks for posting this wonderful tutorial. I’m enjoying it immensely, and learning a lot about how to do things in Blender. I can see this being very handy for doing preliminary modelling of things I actually want to build.
One thing I am wondering about is camera angles for overall visualising of models, mainly in terms of correct perspective. Which camera angles and other settings have you found give the closet approximation to the way the human eye would see the same full-sized object?
