Carlo,
draw it as a fusion object than it is obvious what are the
intersections:

\documentclass[11pt]{article}
\usepackage{pst-solides3d}
\begin{document}

\psset{unit=2.0}
\begin{pspicture}(-2,-2)(2,2)
\psset{viewpoint=25 20 45 rtp2xyz,Decran=20,lightsrc=viewpoint,solidmemory}
\axesIIID[linecolor=blue](0,0,0)(4,5,4)
\psSolid[object=plan,definition=equation,
   args={[1 2 -1 1]},
%    args={[1 0 0 -1]},
    fillcolor=blue!50,
    base=-2.7 2.7 -4.0 3.5,ngrid=30 30,
    action=none,
    name=Plane1%,showBase
    ]
\psSolid[object=plan,definition=equation,
   args={[1 1 1 0]},
%    args={[1 0 0 -1]},
    fillcolor=red!50,
%    plansection={[1 2 -1 1] [1 3 1 2]},
    base=-2 2 -2.5 2.5,
    ngrid=30 30,
    action=none,
    name=Plane2, %intersectioncolor=(bleu)%,showBase
    ]
\psSolid[object=plan,definition=equation,
    args={[1 3 1 2]},
%    args={[1 0 0 -1]},
    fillcolor=blue!50,
    base=-0.85 2.57 -4.7 2.5,ngrid=30 30,
    action=none,
    name=Plane3%,showBase
    ]
\psSolid[object=fusion,base=Plane1_s Plane2_s Plane3_s]
\end{pspicture}

\end{document}
