kerning & metrics

you know, sometime have a mistake for kerning & metrics. but i decide to make from scratch. how i can do the kerning & metrics going the value to zero like an early first create both (kerning & metrics) have no value? *i use auto kern & auto metrics

There are a couple of ways to set all LSB and RSB to zero.

Solved ( i just clarify to my post are that are solved, so i can understand)
