Obscure Key-In You May Want to Know

I'm getting to the point in my CAD-life where it is a novelty to learn completely new tricks in base AutoCAD. But today I did, and here it is:

CONVERTCTB

Use this to convert a standard color table (CTB) to a style-based table (an STB).

Then, once you have an STB made, you can force your drawing to recognise the style table by typing:

CONVERTPSTYLES

ACAD will ask you if you really want to do this. Say yes. It will take a few minutes to kick in.

What does this mean? It means that you can now set plot styles by layer rather than by color. In other words, if Bob likes his "Roadway" layer to be Cyan and Sue wants her "Roadway" layer to be Magenta, they can plot the same shade of gray.

Oh happy.
