The software calculates area studies in two phases. The “sub-study” portion is the second phase of the study calculation. The tool builds the underlying map view based on the first phase calculations. Unfortunately, you cannot turn this off, but you can change it to run more quickly and give you more coarse results.
To do this, navigate to Studies menu>Define Menu>Define Study Grid. When the dialogue dialog opens, adjust your grid point spacing. The sub studies are related to your study grid resolution. The more fine your grid point spacing is, the more sub-studies will run , and the longer it will take. As a result, your map will look better visually.
