我正在尝试表示多面体，但 GhostScript 似乎不允许我对立方体进行多次切片。具体来说，我尝试了以下操作：
\psset{unit=0.6cm,labelsep=20pt}
\psset{viewpoint=150 -110 10 rtp2xyz,Decran=120}
\begin{pspicture*}(-5,-1)(15,20)
\psset{solidmemory}
\psSolid[object=cube,action=none,a=10,plansepare={[1 1 1 -3]},name=A](5,5,5)
\psSolid[object=load,load=A0,plansepare{[1 1 0 -2]},action=none,name=B]
\psSolid[object=load,load=B,action=draw**]
\composeSolid
\axesIIID[axisnames={A,B,C}](0,0,0)(11,11,11)
\end{pspicture*}
上面的代码可以编译，但当然只显示第一次剪切的结果。如果我将最后\psSolid一行替换为
\psSolid[object=load,load=B0,action=draw**]
然后 GhostScript 失败并给出以下错误：
