(括起区域)Bracketed area percentage — Is the total area between negative to positive of the draft angle. In this case, the bracketed area percentage is within the angle - 4 to + 4.
The total area of the cube, which has 6 surfaces is 61061.9.
The total area within the range of - 4 to + 4 ,that is, the positive value is 40537.8.
The percentage of the bracketed area is calculated as follows: Bracketed Area Percentage = Positive value/Total area of cube * 100
In this example, it is 40537.8 / 61061.9 * 100 = 66.3881.
(预估最大错误区域)Estimated maximum error percentage — Is the total area within the range - 0 and + 0.
The total area of the cube, which has the 6 surfaces is 61061.9
The total area within the range of - 0 to + 0 is 305241.1.
The estimated maximum error percentage is calculated as follows: Estimated maximum error percentage = Verticals / Total area * 100.
In this example, it is 305241.1 / 61061.9 * 100 = 49.9888. |
