I received the following question today while in my hotel room in LA and wanted to write a blog post with images to make the solution more clear, and perhaps assist others with the same question.
“My background in paper space is white with color lines, I want to change the color lines to black lines, I did once but is impossible to remember how I did it.”
What we want to do is change the Layouts Plot Style to black and white which is “monochrome”, and then select the option to show the Layout with the applied plot Style just as it will plot.
A Layout is essentially what you plot as a large preview, think of it as a piece of paper. Here we see the drawing with a white Layout background just like paper and the color layer based lines. The only thing not shown is the plot style you may apply to the Layout. In this case we want the color line work that will use the monochrome Plot Style to show as Monochrome in the Layout.
Use the Page Setup Manager. I used the PAGESETUP command at the AutoCAD command line or you can right-click on the Layout tab and select Page Setup Manager.
Now select your layout then select Modify.
Select OK and you are done.
