First let me show you how to convert Fischer projection to Newman projection. The easiest way to do this is to proceed via Sawhorse projection (if you are aware of that). However you can convert the projection directly also. In Fischer projection, the crosses or the intersection represent the chiral centres of the molecule. However, we are considering 1,1-dichloroethane which has no chiral centre.

Now while converting a Fischer projection to Sawhorse, please remember that the resulting structure will be eclipsed in nature. This is the general rule of fischer to sawhorse conversion. However, you can skip the eclipsed structure once you are adept with the projection formulas. The horizontal bonds will remain above the plane. The lowermost carbon centre would be the one closest to you. Notice that in Sawhorse, there's no separate distinction for chiral centres. Any two adjacent carbon centres can be considered for Sawhorse projection.
