OK, I found something in the documentation and the example-code.

When I use plenv() to set up the 2D grafics and then
use pklw3d() and plbox3() I have the 3D-graphics
activated, but I have the 3D axes as well as a 2D axes
in the picture.
When I throw out plenv() I have a blank page, even when using plvpor()
and plwind().

Possibly I have only wrong parameters so that the 3D-stuff is located
somewhere else but not in the viewable area.

Where is it explained, what is called world-coordinates and user
coordinates?
It's used very often in the documentation, but I have not found an
explanatory text that describes the concepts in general,
before applying them in the documentation.

When I used plenv() to get a viewable axis in my output,
the (x,y,z) = (0,0,0) of that 3D-axis is located somehwere
beyond the viewable area, so that I only see the top of
that graphics.

How can I translate the 3D stuff to the middle of the
graphics?


TIA,
