Robert,

Here is a plot:

Graphics3D[{Cuboid[{0, 0, 0}]}]

In the Output Cell, place the curser before the plot and type
"AbsoluteOptions[". Then after the plot type ", ViewPoint]". This will turn
the Output Cell into an Input Cell. You can then evaluate to obtain the
Viewpoint. You can actively rotate the plot to obtain new values upon
re-evaluation. You could also use a list of options.

Hi,
in Mathematica V 5.2 there was a useful graphics tool being envoked by Menu
> Input > *3D ViewPoint Selector*. With this interactive palette/notebook
one could easily determine the Cartesian or Spherical coordinates (i.e.
{theta, phi, r} resp. {x,y,} ) of a wireframe cube and then paste these
values for the optimized view of the rotated cube into another Mathematica
graphics.

Unfortunately this tool became obsolete from version 6.0. on (which is
mainly due to the fact that 3D graphics can be manipulated interactively in
higher Mathematica versions.) Nevertheless, in order to determine the
optimum viewpoint coordinates I sometimes miss this tool. And I just
searched in the installation tree structure of Mathematica V5.2 (and higher
versions too) for a notebook resp. palette with the name 3DViewPointSelector
(or similar) but could not find this tool even in V5.2. Of course, one could
write a litte application with Manipulate for rotating a wireframe cube and
read out the viewpoint coordinates.
But if this tool already exists why do additional efforts...

Does anyone know where to look for this nice graphics tool which (if
available) would certainly be applicable in other Mathematica versions too.
Help would be appreciated.

Thanks R. Kragler
