Similarity of LMB (Least Material Boundary)

[ivanginato]

I'm venturing on learning GD&T alone. When reading about Least Material Boundary I've concluded that least material boundary is equal to the outer boundary for a hole (internal feature)and equals to the inner boundary for a shaft (external boundary). Is that rigth? Could I consider the least material boundary scenario as the scenario where there is the biggest clearence?

Yes, but note that LMB is as related and assigned to a Datum Feature.

No... too general except for selected cases.
