[pstricks] slicing a cone

[Nitecki, Zbigniew H.]

I tried to look at the example 28 in
http://tug.org/PSTricks/main.cgi?file=Examples/Gallery3D/Gallery3D
<http://tug.org/PSTricks/main.cgi?file=Examples/Gallery3D/Gallery3D>but when I downloaded the file and tried to compile I got the error message
./exa028.tex:58: Undefined control sequence.
<recently read> \c at lor@to at ps



l.58 \axesIIID
              [linecolor=blue](0,0,3)(8.5,4.5,4)

Now, I know that \axesIIID is a perfectly good macro in pst-solides3d (which is the package called by the file) so I have no idea what I am doing wrong.  I am a bit desperate to find an example to work from, since my own attempt (using object=load as given in the pst-solides3d documentation, English version) seems to lead to some kind of infinite loop.  Any suggestions, either how to modify this one so it works, or another place to find a working example?  I am interested in precisely the kind of picture in the example cited (perhaps with some details, like grid, changed): a double cone sliced by a plane not parallel to the coordinate planes, showing the intersection surface (and eventually projecting some lines onto the slicing plane).
