This command finds the largest circle centered inside the sample area that does not overlap any existing sample locations.
Options:
The find command uses the Accuracy number as a grid spacing for its scanning algorithm. The smaller the spacing, the longer the search takes, but the more accurate the resulting size and location of the spot.
You can choose to keep the spot from overlapping vertices of the sample area as well as sample locations.
You can choose to keep the spot entirely within the sample area or allow it to extend beyond the boundary.
