[pstricks] hidden lines in pst-solides3d

Dear Zbigniew,

within \codejps you cannot use the PSTricks commands -- you need to use 
the codejps commands.

So a multido will not work like you have set it.

There is another _non-codejps_ way to fusion some objects -- see the 
syntax of the following code:

\psset{lightsrc=50 -50 50,viewpoint=40 16 32 rtp2xyz,Decran=40}
\psset{unit=.6}
\begin{pspicture}(-6,-5)(6,7)
\psset{solidmemory}
\psSolid[object=cylindre,h=6,fillcolor=blue,
      r=1.5,
      ngrid=4 16,
      action=none,%otherwise it is drawn as well  nonfusioned
      name=A1,
      ](0,0,-4)
\psSolid[object=anneau,h=6,fillcolor=red!50,
      R=4,r=3,h=1,
      action=none,%otherwise it is drawn as well  nonfusioned
      name=B1,
      ](0,0,-1)
\psSolid[object=fusion,%here you fusion the two objects
      action=draw**,
      base=A1 B1,
      ](0,0,0)
\composeSolid
\end{pspicture}


Your problem is quite complex to realize, due to a FUSION with multido 
-- you need unique names for each of the vectors which could be handled 
with a natural counter etc. and then put the fusion object within 
another multido environment ... These my ideas, however i  failed with 
that.

Sorry that i couldn't help, however Manuel is very tricky in such things 
-- maybe he knows an easy solution.

Regards,

Juergen
