Hello,we receive xref CAD files and pdf  which imported from REVIT, the pdf files black and white except the hatching is colored.the cad files all the lines are colored, how can i plot these CAD drawings after modification to B&W and the hatching colored without changing  or exploding the drawing from colors to b&w before plotting.

Find what the colors of the Hatch patterns are, and edit the Plot Style Table (pen assignments) so that those colors plot as black, with lineweights as appropriate to the graphic intent.

thank you Kent,I want the hatch color to be colored as they are. They are about 12 colores in the entre drawings but the other lines colors thousands.I tried to create a new plot style but I can not change all the colored lines to black, there are a lot. Is there an easy way to keep all the lines black but the hatched colors as they are?thank you
