RE: Basic
1.1.1 is the Aresti Family code for the line that the roll is placed on and 9.1.3.4 is the Aresti Family code for the roll. The 2 in the next column to the right is the K factor for the line element, the 8 in that column is the K factor for the roll element. The 10 in the last column is the combined K factor for the complete figure.
