[pstricks] pst-3dvue and \psset

[jmpapy]

Hello everybody,

The attached code draws a cube with bars inside. It compiles fine. The
only problem is when I change the unit value with \psset. For instance
when I set unit=0.5cm, only the external cube is reduced and not the
bars. The bars are drawn in the \multido loop. Does it have something to
do with multido ? pst-vue3d ?

thanks you very much
