There are two kinds of blockings, Active blocking and Passive blocking. Active blocking is a way that

fixed at ‘Boxing Center’ of the frame. The examples of active blocking and passive blocking are as

The edger shows movement amount of the optical center for blocking on the screen. Active blocking is
much easier than Passive blocking for blocking. However, active blocking has some limitations, which
