Using Square Symbol on a square hole pattern
Has anyone used the square symbol to define the shape of a square hole pattern? Definition from ASME-2009
[B][FONT=MetaPlusLiningBold]3.3.16 Square Symbol[/FONT][/B]

The figure in 3-18 shows an example using the square feature on an external feature of size. I don't see why there would be any reason not to use it on a square hole pattern, or tolerance zone.
