Here are five ways to do it that I can think of, they aren't elegant solutions and they are all manually adjusted except #4 and #5:
- Create a balloon note(Creo 2.0). May have to add a space before and after the number to get a matching balloon size.
- Create a custom balloon symbol.
- Create simplified rep copies of the master assembly and a BOM table for each copy, match the BOMs, move the BOMs off the printable margins of the drawing. Highly inadvisable.
- I haven't tried this method...use the reference balloons but place an offset filled square over the "REF" and change the line style to a color that doesn't print...use a pen that doesn't print. I don't know if this would work or not. At least the number would always update correctly and automatically.
- Just get everyone accustomed to seeing a reference balloon.
I recommend #5.
