No, this is the syntax for the common 2D graphics. For pst-3dplot macros 
the three coordinates must be comma separated, but can contains 
Postscript code (see below)

After your reply I tried this at home and also got a Postscript error. 
However, in the office the following example works:

\listfiles
\documentclass{article}
\usepackage{pst-3dplot}

\begin{document}
\def\PhiI{70}
\begin{pspicture}(5,5)
\pstThreeDLine(0,0,0)(2 \PhiI\space cos mul 1.5 add, \PhiI\space sin,0)
\end{pspicture}
\end{document}
