New GD&T Profile Tolerance

New GD&T Profile Tolerance



[cid:image001.png@01CF4E79.95116BF0]

A new symbol, circle U, was added to profile tolerance. In the past, a design engineer wanting to specify an unequal profile tolerance on the drawing would draw a chain line in the applicable area. Two arrows were shown to displace the tolerance zone. In the new standard, the circle U symbol follows the toleranced value in the profile feature-control frame. This announces that an unequal tolerance is in effect.

Is there some way to add this to the interface?

It's almost 5 years since ASME added the (U) symbol and almost 10 year since it was first proposed. If it's not there now...


Besides, the chain line is more direct.

A circle U is used in ASME, ASME Y14.41-2003 to be exact.It refers to the distance from the surface a profile tolerance is offset. A distance of 0.000 means that the tolerance is bilateral.This does away with having to draw a phantom line to denote which side a profile tolerance is applied to.
If its not a standard in the ProE drawing call out make a symbol

You can turn this on in the drawing options.
