1. Raster width Box lt Table gt 01 3 There are three ways to respond to this prompt You can 1 type in a value as the width to be used for all vector lines to be rasterized for plotting 2 use the LineWidth Configuration Table to correlate AutoCAD color numbers with line widths or 3 use the Box option to specify a standard linewidth graphically Fixed Line Width a You can type in a value in mm or inch as the width to be used for all the vector lines to be rasterized The value in parentheses is the default value or one previously used If you enter a value it will remain the default line width during this editing session Note If you defined the width earlier in the session that value will appear as the default You can press RETURN to accept this value or enter a number to represent the new width The selected entities will all be converted to raster with the designated width Using the LineWidth Configuration Table a If you type in T or Table the LineWidth Configuration Table appears The listing correlates AutoCAD color numbers and line widths expressed in current units b If you defined the width previously in this session with a typed value or the box option that value will appear as the default You can press RETURN to accept this value or enter a number to represent the new width The selected entities will all be converted to raster of the designated width Note The original default
