Rank is a numeric setting that allows tool paths and knowledges to be ordered in the code according to value, lowest to highest. When sorting by rank, the lowest rank number is cut first. You can make a tool path with rank 1, then another with rank 2. If you want a tool path to go between 1 & 2, make this tool path rank 1.5. Simply fill in a rank number before making a cut. Also note in the following sorting tasks, that area is defined as starting with the smallest and going to the largest.
