Help with diamond/silicon crystal structure

[RageCoder2006]

i wanted to make a silicon crystal structure. i imported the .cif file of Si and it created a primitive unit cell, after creating a supercell of 3x3x3 it just gave me 9 atoms of Si, but not in the structure of diamond lattice, i am new to the program and might be missing some info. would like some help. here’s the same thing i tried with .cif file of diamond.

this is how its looking like and not like the image below:

When you import the crystal structure, you will get the symmetry unique atoms. Before creating a supercell, you should “Fill Unit Cell” (under the Crystal menu).
