Drafting Balloons

[baazar]

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

You would get better response by red-flagging this post and re-posting in the SolidWorks forum.

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.

1. This question might be better for forum1103. 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. 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

lumenharold, while part 3 of the post is probably best in the forum you mention, I'm not sure about the other parts of the question.
