What's the proper way to call out a tabulation block?
(OP)
We need to make a bunch of parts and they're all exactly the same except for one hole. About 50 have a .060" hole and the other 50 have a .039" hole. What's the best way to call out 2 different dimensions for the "same" part/feature? Tabulation blocks?
Do you dimension the hole with "A" and then just have 2 different dimensions in a table? Or is there a different way to call it out?

In either case, it sounds to me like these parts should have separate part numbers. Which means separate drawings.

Pretty much does what MM says.

RE: What's the proper way to call out a tabulation block?
I'll echo previous responses and say that a tabular tabulation table is likely the best approach.
Another approach I've seen used, particularly in cases where only a single dimension is variable, is to directly use the numerical value of the dimension (in appropriate units such as thousandths of inches) as the part number suffix (dash number). A drawing note would explain the scheme.
I'm not sure what, if anything, ASME has to say about this method. If anyone happens to know, I'd be interested to hear.

If more of the shape can be tabulated, you can reduce the number of drawings.
