CST - Local meshing in a hexahedral mesh?

I've been trying to implement a local mesh in a hexahedral meshing. The procedure itself went through, but when I actually viewed the mesh, meshing density was the same all over the model. Consequently, it increased the mesh number a lot more than I wanted. I know how to do local mesh in tetrahedral meshing. But for the hexahedral, does any one know how to do local meshing?
