You are right, thank you for this note. This functionality in v.5 is
exactly what I need. It works perfect in v.5 but in v.6 and v.7 such
functionality is absent and this means that I should go back to v.5
which does not take advantages of new graphics capabilities of version
7.

You are right.

In really it is possible (and it is not too difficult) to optimize the
number of points in the 2D-projection of complex 3D-line plot and such
vector graphics will have size in 3-20 kilobytes - much less than
bitmap and of high quality! But it is really simple only inside
Mathematica and having real 2D-projection of all points AND axes with
ticks and labels... The latter is problem in v.6 and v.7 but in v.5
all of this is created automatically. The lack of such functionality
in v.>=6 is painful.
