[pstricks] Problem with fill in 3dplot

[Martin Chicoine]

How can I get the color to fill only the shape in the following example?

 

\documentclass{article}%

\usepackage{pst-3dplot}%

 

\begin{document}

 

\begin{pspicture}(-3,-2)(2,2)

  \pstThreeDCoor

  \pscustom[fillstyle=solid,fillcolor=red]{

    \pstThreeDLine(0,0.2,0.2)(0,0.2,2.5)(0,0.4,2.5)

    \parametricplotThreeD[liftpen=2](0.4,3){0 t 1 t div}

    \pstThreeDLine(0,3,1 3 div)(0,3,0.2)(0,0.2,0.2)

  }

\end{pspicture}

 

\end{document}
