3)  pair-wise offsetting method
边等距法
1.
Currently,the most widely used offsetting method for closed 2D-compound curve is pair-wise offsetting method,the disadvantage of this type of methods is that they can not deal with closed 2D-compound curves with islands very well,and the efficiency is expected to be improved.
