Dear all,

As a beginner, I would like to construct a crystal with multiple special surfaces (the size is around 100nm) and using Material Studio to do some simulation. One typical example is shown below: an octahedron with eight Si{111} surfaces.

But it seems difficult to even construct such a model system in material studio. The "cleave surface" function could only cut out one surface and I got stuck...

It would be very helpful, if any expert could give any general method to construct such a crystal with multiple desired surfaces? (The {111} surfaces are replaced by other crystal surfaces)

Thanks in advance!
