Adding Color to your B/W drawings
If you produce construction documents, chances are the majority of your work is produced in black and white, for eventual printing and/or reproduction on a monochrome printer. If you use color dependent plot styles, then your default CTB file may be set up so that all of the ACI colors (1-255) plot black.
So what do you do when you need a one entity or one layer to show up in color for a special plot? You could create a separate CTB file where some colors are set up to plot in color. But there is a way to do it without even switching CTB files. Change the object(s) or layer color to a Truecolor.
Truecolors are not affected by the CTB file, so they will always plot in the same color as shown on the screen. Lineweight is determined by the lineweight assigned to the object/layer instead of the CTB also. Give it a try.
