Hi,I need to send a pdf of my dwg file but want everything to print monochrome except one layer. I have around 70 layers on the dwg - is there an easy way to change the colour of all the layers at once and then change the layer I want to highlight afterwards? I need fire alarms and lighting etc to show up and don't want the pdf to print in all colours or all black as it would get lost.Cheers,Alec

Edit the monchrome.ctb or stb plot style file (whichever you use) and change the color of that one layer from black to red then save this new style using a different name.  All the layers except the one you changed should print in black.

If you are using a ctb file for plotting, for the layer you want in color, set the layer color to a "true color" and it will plot in that color.

Many thanks gents, sorted it. So much quicker than changing 70 layers!
