hi dingfang zeng,

could you provide minimal examples?

I tried out the following:


  \def\phii{1}\def\phiii{2} \pstThreeDLine(\phii,\phii,\phiii)%this  
compiles ok with my system
%\pstThreeDLine(\phii 2 add,\phii,\phiii)%this not

%\pstThreeDLine(! 2 2 2 2 add)%nope
\psline(! 2 2 2 add)%compiles
%\psline(! \phii 2 2 add)%no
%\psline(\phii\space 2 2)%no ----> hint from other list-member

so it seems to be that in the 3D-case you cannot make computations  
like mul, add etc., but you can use your definitions.

in the 2D-case you can make computations, but not mixed up together  
with your definitions.

I'm not sure if there is any possibility to make computations (which  
are carried out by postscript) together with definitions made in the  
LaTeX-code, even in 2D-geometry.

for your other problem I have no time to study it at the moment,  
sorry. but for sure herbert will look into it soon.
