+\section{Positioning a solid}
+
+\subsection{\Index{Translation}}
+
+The following command~
+\texttt{\Lcs{psSolid}[object=cube,+\textit{options}](x,y,z)} shifts the
+centre of the cube to the point with the coordinates $\mathtt{(x,y,z)}$.
+
+The next example will copy the cube with edge length of 1
+\begin{pspicture}(-0.5,-0.5)(.5,.5)
+\psset{Decran=40,viewpoint=50 35 35 rtp2xyz,a=1,lightsrc=50 30 20}
+\psset{fillcolor=yellow,mode=3}
+\psSolid[object=cube](0.5,0.5,0.5)% c1
+\end{pspicture}
+to the points with the coordinates $\mathtt{(0.5,0.5,0.5)}$,
+ $\mathtt{(4.5,0.5,0.5)}$ etc. so that the copied cubes setup the vertices
+ of a new cube with the edge length 5.

+\psSolid[object=parallelepiped](0.5,0.5,0.5)%
