I have been reading about the projection conventions and am not sure
if I completely understand them. I know the third-angle convention is
preferred in the US and Canada and the first-angle in Europe. I have
also seen the descript that the object is above the screen in the
first angle convention and below the screen in the third.
Say you are shining a light through a translucent object onto a
screen. Is the third-angle projection what you see on the screen from
the object side and the first angle projection what you see if you
stand on the opposite side of the screen from the object - or is it
the other way around?
Many thanks in advance,
Peter.
