Find numbers in drawing notes
Find numbers in drawing notes
(OP)
Hello,
This is my first post, although I've "trolled" for a while and have learned a lot from this forum.
My question is this: I do the drawing checking around here (among other things). Consider a "normal" assembly drawing with an integral BOM table and balloons calling out parts on the field of the drawing. Our CM manager claims that if a drawing note speaks about a find number of a part already called out via a balloon, it has to be in parenthesis, since under this circumstance it must be considered reference (due to the fact that it's already been called out via a balloon). Such as, "Bond (FN 1) with FN 10 per manufacturer's instructions". If a find number 1 balloon exists in the field of the drawing, he says it must be in parenthesis in the note. I've never heard of such a thing, and in my mind, the note is not "calling out" the find number, but simply applying an instruction to it. This seems (and looks) silly to me, and I've not found anything like this in ASME or any other standard. Can anyone comment on this?

I may be wrong, but that is how I remember it.

I am less concerned about the official procedure than I am about someone updating the drawing and not screwing up the information. A lot of drafting rules were worked out on drafting boards. I am presently on SolidWorks.
- Do not type item numbers and part numbers in your drawing notes. If the model that controls this information changes, your notes will not update. In notes, I refer to parts by copying whatever description is used on the BOM. This is less likely to change, and may still be meaningful if changed.
- Whenever possible, if your CAD software allows you to attach model information to your notes, do it that way. These should update reliably.
- With 3D CAD, consider attaching your notes to the relevant drawing view. This gives you more opportunity to capture information from the CAD model in an automatic updating state.
Putting part and item numbers in brackets sounds like a good idea, except that this is a standard for dimensions. If I saw a note like this, I would not be sure of how to interpret the brackets. If the CAD model changes and the note does not, the drawing user will be just as confused.--

NOTES:
1. BOND (FN1) TO (FN6) WITH FN 10.
Where find number 1 and find number 6 have already been designated in a view with a balloon.

This is a perfect example of something that should be attached to a drawing view. I do not how your CAD works. In SolidWorks, I would go to the view, and attach item balloons to the parts. Then, I would attach a note to the parts, click on the item balloons, and type in my text. I would then delete the original item balloons.
At this point, you would see a part ballooned as FM1. You would see a second part with a note attached to it, calling it FN6, and stating that it is to be retained with, oh, how about THERMAL EPOXY. I place adhesives and other chemicals at the bottom of my BOMs. There would be something on the BOM that obviously is thermal epoxy.
