Repetative Dimension Quantity within Detail View
Repetative Dimension Quantity within Detail View
(OP)
This question is so basic I can't find where it is even defined or discussed, but would really like to know the correct answer. Please state a reference if possible.
1) If defining a "repetative dimension" (ASME Y14.5 term inside the "") within a detail view, should the "number of places" be the total number of places on the part, or the number within the detail view? For example, if a part has 3 slots, and I'm showing the 10 mm width in a detail view showing only one slot, would the dimension within the detail view be called out as 10, or 3 X 10?
2) Should I do anything on the detail view to indicate quantity? For example, 3 X Detail A, Detail A (1 of 3), etc?

I haven't re-read all the replies, but if I recall there was no explicit reference from the Y14.5 standard. (Someone there referred to Fig. 7-37 of the standard, which shows something about details views, but maybe that's not what you were asking.)

You may have 3 patterns of 4 holes to appear on 3 different views. You can call the holes 4X on every view or 12X just once. As long as total quantity is correct, you drawing is correct. (There still a question of possible misinterpretations, how easy it is to mistake different holes for each other, etc.)
And yes, if you have “pattern of patterns” shown all on the same view, the Fig. 7-37 is the way to go.
