When it Comes to Dimensions - Give the Customer What They Need
(In accordance with Y14.5M-1994 standard)

PDF of this Tip

I received a comment on April’s 2000 Tip regarding the placement of dimensions on the drawing. At issue was the 30 BASIC dimension. Notice on the revised drawing that the 30 has been replaced by the 21.21 BASIC dimension at the 45° angle. The comment came from someone who inspects parts. His point was that in order to inspect the part, he would have to calculate this dimension. The actual part definition and tolerance have not changed. Since inspection receives and must use the print, they are design’s customer. Why not satisfy the customer by giving them what they need if the actual requirements do not change.
