I'm working on a drawing with staging of works on it. I have 3 drawings for the 3 stages, and each stage shows the work done as part of the previous stage. However we would like the work from previous stages shown, but printed as grey rather than black.
I know how to set certain colours to print grey while the rest are black, however is it possible to modify the plot table so that particular layers rather than colours can be changed to greyscale?
