ANSI Y14.100 and DRM state to use QTY REQD next to a find number ballon to indicate the quatity for the callout in the body of the drawing. We all agree to this practice here. Ex. For an assembly that requires a bolt, two washers and a nut, we would show 3 stacked ballons with "2 REQD" next to the find number for the washer.
Where we have an argument is how to show that this combination is in multiple places in the assembly. One camp wants to bracket the stacked balloons and but the number of places this occurs as "3 PLACES". Another camp agress to the bracket but wants to use "3 REQD". A third camp says no bracket, just put "3 PLACES" underneath the stacked balloons. (My preference)
Nobody can find any ANSI or global specification that specifically address this. If none exist I say add one of these methods or something similar to our local specification to end all of this bickering. All three camps want it their way. If someone can point to a recognized spec we can end this now.
