1.Extend Face
2.increase Hole Depth
3.Extend this face by 0.4mm.Current face offset is 0.6mm ,so reduce to 0.2mm overall
4.Increase depth of this blind hole so chat minimal amount of material remains (0.5mm Max)
5.Current Offset is 0.6mm.Reduce by 0.4mm so that
GREEN FACE is 0.2mm

1.Extend Face 延伸该面
2.increase Hole Depth 增大钻眼深度
3.3.Extend this face by 0.4mm.Current face offset is 0.6mm ,so reduce to 0.2mm overall
将此面延伸0.4毫米，而现在的表面补正是0.6毫米，所以合计起来就是缩短到0.2毫米
（理解：大概是一个柱状结构，在设计时进行长短伸缩调整）


4.Increase depth of this blind hole so chat minimal amount of material remains (0.5mm Max)
加深这个盲孔，这样留下的材料最少（？） 最大深度为0.5毫米
5.Current Offset is 0.6mm.Reduce by 0.4mm so that
GREEN（应为current?） FACE is 0.2mm
