Different Depths while carving

Hi, I pretty new and I’m trying to figure out Easel along the way and I was wondering how do you change the depth of cut partially through. For example if I typed the letter K, the bottom half engraved 1/4 inch deep while the top half of the letter cut out completely. I appreciate any guidance or tips you can send my way.

can you share your project so we can look at the file? And a picture of the carve as well.
