(2) a fixed area of flat ground rules: Fixed rules of flat ground floor building area = area
3, Note
(1),
la gear sneakers, fixed rules in some areas of flat ground area: external skin line by putting 2 meters calculation. Calculation by putting the external walls of 2 meters outside the line of block graphic terms, and then combined with the bottom floor area; or press the . So there will be as difficult calculation:
①, divided block is too much trouble, some hard to deal with the arc, prone to error.
②, 2 meters of the centerline of arithmetic more difficult, not calculation.
③, putting 2 meters after the overlap may occur, in the end should not calculate how much less.
