I am quite new to GD&T and have two questions on position tol of holes.1) I have holes on two opposite sides in a rect block. How does one do a position tol on the holes? Do I use the left side as primary datumn for holes on the right and vice versal.2) Sheet metal has different tol for its features. That is hole to hole, hole to fold, edge to hole and etc have different tol control. How does on keep a hole pattern within tol from a folded side? Do I position tol like I normally would in a machined part or I reference a hole to the fold side and than position tol all the holes to that hole?
thanks in advance
