Definition: Wedge and Dash Projection is a means of representing a molecule (drawing) in which three types of lines are used in order to represent the three-dimensional structure: (1) solid lines to represent bonds which are in the plane of the paper, (2) dashed lines to represent bonds that extend away from the viewer, and (3) wedge-shaped lines to represent bonds oriented facing the viewer.
