Used to setup the Line Mapping Settings. Match Line Mapping Settings sets the Working Units section using the current zoom factor to determine the size for each Line Weight and Style.

Since Line Weights and Styles always display at the same ratio regardless of the zoom factor, for each level of zoom, the element covers more or less pixels. Therefore, when zoomed far out, the element covers more pixels than when zoomed in. It is this coverage, in Working Units, that is used to modify the Line Mapping Settings. This allows a constant ratio between View display and Raster Resolution.
