These settings are used in vectorization to specify vector line widths, layer assignments, and the handling of non-continuous lines.
You can use the Width Table to automatically assign layer and polyline width values to the vectors based on the width of the original raster. In this table, you specify how to handle lines of particular width ranges. Lines of a different width are assigned the default values for layer and polyline width. You can also specify default values for non-continuous entities, such as dashed lines, that override the values specified in the width table.
