Drafting Balloons

Drafting Balloons

Drafting Balloons

(OP)
I'm a green engineer and am recreating some professionally done drawings (from ProE) in Solidworks and have encountered an issue.  From what I can tell, Solidworks has no trapezoid balloon feature, just circle, triangle etc.  This company that originally did the drawing used a trapezoid balloon.  My questions are the following in order of importance:

1. Where can I find out what the different balloon shapes mean? (ANSI/MIL standard etc.)

2. What does the trapezoid flag indicate? (as opposed to square, triangle etc.)

3. Is there a way to make custom Solidworks balloons?

TIA - Bram

RE: Drafting Balloons

(OP)
I figured with the lack of response that it might not be the best post, but I figured it has more to do with MIL-STD-100 or possibly ANSI Y14.5M-1994 (or something equivalent), neither of which do I posses.  

RE: Drafting Balloons

1.  This question might be better for forum1103: Drafting Standards, GD&T & Tolerance Analysis.  However, as I recall there isn't a whole lot of info about balloons in the ASME Y14.100 series docs.  ASME Y14.5-35M-1997 talks about use of balloons for revision symbols and only mentions round balloons thread1103-273831: REVISION SYMBOLS.  14.100 4.26.6 f gives some examples of Flagnote symbols including rectangle, hex & triangle but doesn't say much - if they were flagnotes then there should be the same symbol around the number in the main notes block.

2.  Most likely it's defined by a company spec, or at least general practice from whoever originally did the drawings.  Except as mentioned above for rev symbols I don't think the ASME stds generally spec what shape balloon is used for what - as long as each different purpose is different.

3.  This question might be better asked in forum559: SolidWorks 3D CAD products
