If you’ve messed around with the Surface Analysis styles at all, you might have noticed that you cannot make the hatch anything besides solid colors.
Did you know that you can have your .ctb help out?
Assign colors to your analysis that you can make “special” in your ctb. (I am using 1,2,3,4,etc. just to make it easy for this example)
Edit the “Fill Style” portion of your ctb (or you can make a special ctb just for surface analysis)
Plot using that .ctb and check out the magic.
Special thanks to the puppetmaster. You know who you are.
