I may be ignorant or just palin stupid, but I have a drawing that shows unless stated a tolerance of +/- 0.05mm. I understand this to be if a size is 100.00 nominal the top size is 100.05, bottom size 99.95. I am having a bit of an argument with a contractor on this. It is one of his drawings. He claims the top size should be 100.025 bottom size 99.975.
Who is right? Thanks.
