A wedge and dash projection is a way of writing organic molecule to represent three dimensional structures. The Wedge-shaped line represents bonds oriented towards the viewer and Dash line shows bonds pointing away from viewer. The Solid lines show that bonds are in the plane of the paper.
It is a diastereomer of "A". Now, let's change the configuration of just "C3" to get Compound "C". This is also a diastereomer of "A". BUT, if we change the configuration of both carbon atoms, we get Compound "D". This is nonsuperimposable on "A". However, it is a mirror image of "A", because both "OH" groups are on dashes instead of on wedges.
The gauche interaction occurs in butane occurs when the two methyl groups have dihedral angles of 60° and 300° and arises because the methyl groups are still quite close together (about 3.1 Å, compare to 2.9 Å) for the syn – conformation.

It is an odd point of view looking down the end of a bond, and so it is very easy to add or lose carbons. How to: In the Newman projection, we are looking down the bond between two adjacent atoms. We only draw the front atom. The second atom is obscured behind the first.
