I have a contour plot that took a few hours to evaluate. Is there a way that I can show only the contour lines of a specific value without re-evaluating the contour plot?
To isolate a contour line of a particular value, you could use
Then how do you extract the desired contour? Here is a manual way that always works as long as you can visually pick out the contour you're interested in:
What I've done above is to display the graphic for the contour plot in a very bare-bones way. Then I double-clicked on the graphic to activate the Drawing Tools. They allow me to select a particular contour by double-clicking again. If you get the contour to be highlighted as above, you should be good to go for the next step:

For this to work, it's important to convert the contour plot using
