Put a view of a part in a drawing, add a SW BOM to call out the material, such as FLAT BAR, 3/8" x 4" HRS. Now, say that you have 5 of these on a drawing and so you start the numbering of the first BOM at 1, the second at2, etc. Then some people like to balloon the single part in the drawing view and expect it to match whatever is in the BOM field. It doesn't.
Is there any rhyme or reason for this? I figure that the balloons are inserting and being controlled in the order they occur in the model file, which in the case of a part file will always be 1. But you could also make the case that the balloon should automatically match the Item Number field in the respective BOM. I tried it in SW 2005, 2006, 2007, all with the same results.
