Quantities on Item Call-outs

[Slyzzzrd]

One of my co-workers and I are attempting to unify the cad standards at my workplace and we've come to a head over how to call out quantites in item discriptions.

I was always taught that quantites go in parenthasis. If for example, I needed two bent plates, I would call out:
(2) BT PL

My coworker, agrees with me that this looks good, and makes sense, but is convinced it's incorrect nonetheless and insists it ought to be:
2-BT PL

Does anyone know if there is a standard about this, and what it actually says, if not what do you see most often in your experience?

Must be a structural thing, I've never worked anywhere that assy quantities were in the description, they were always in the parts list.

Not many posters in this forum from the structural world, mostly mechanical & aerospace, and I'm not sure this forum has a good record of answering structural Qs. If you don't get a good answer you may want to check out one of the more structures minded forum.

I agree with KENAT.
I would use 2X on the drawing, 2 on the qty column within the PL, or BOM.

Just to be clear if this was a mechanical drawing per ASME Y14.5M-1994, I believe that ctopher is correct.

That being said if this isn't drawn to that standard and I saw both of the OP's examples on the print, I would say the first example is correct,(2) BT PL. A dash is often used in abbreviations and other notes and has very specific meanings, as in thread callouts. I think that there is too much room for misinterpretation by using a dash and would instead use parenthesis.

OP asks about standard, for a mechanical drawing to ASME standards then Y14.24-1999 is the relevant standard. However, I don't think this is directly relevant to most structural drawings.
