==========

We have simulated the electrical properties of 2D films composed of a low conductive substrate (host matrix) and highly conductive zero-width rods (fillers). The rods were randomly deposited onto a plane substrate with overlapping being allowed. Moreover, they were aligned with respect to a selected direction and to a desired order parameter, $s$. To evaluate the filling fraction (or non-transparency), $p$, and the electrical conductivity, $\sigma$, a discretization approach involving a supporting square mesh was used. This approach allowed assessment of the electrical conductivities both of the insulating (low conductive) host matrix and high conducting filler particles. As a result of discretization, the zero-width conducting rods are transformed into conducting polyominoes of different shapes and sizes. It was demonstrated that the polymorphism
