Can any one please clarify my doubt if all the dimension are in positive tolerance that means 14.1,42.4,14.1 then the sun of all will be 70.4 but the over all length is 70+/- 0.2 only that means 70.2
I think, This is to analyse what will be the max and min of that gap. Actual value always depends on variation in other dimensions. This is just an analysis that helps to find what will be the max width of the gap or minimum. Because if we consider that dimension (42) also definitely the drawing is over constrained.
