Hello everybody,

I want to create a line shape with unbalanced tolerance zone. There is always an error.

How to do that correctly in Creo4 with MBD? Thanks!

I think the error in image is because of format for value mentioned after UZ.

If you will define this as 0.3 UZ [0.03], it will not report any error. But if it will be +#.## / -#.##, there will be error. Can you share any image or details about standard which defines this value after UZ.

Hello MaheshSh, you are right. If +#.## / -#.## is changed, only +#.## or -#.## is used, there is no any error. Thank you.

Not sure which standard you're using but ASME Y14.5-2009 shows this entered differently.

Hi @TomU

@sundoopi is using ISO standard for unequally disposed tolerance zone....

Sounds like the basic usage is still the same. The single value after the UZ (or U) just shifts the tolerance zone around. I think he is confusing where the zone is located with the size of the zone.
