User-defined tolerances in %

[[Ma...]]

Hi,

i wonder if you can make user-defined tolerances in percents of nominal value.
I was able to achieve that with this:

<tolerancesPolicyParameter name = "fraction" value = "0.50" />

I am implementing norm "ČSN EN 10243-1" - "Steel die forgings - Dimensional tolerances" - i am interested particularly in radius section.

There is definition:

• R <= 10 _____: +50% / -25%
• 10 < R <= 32 _: +40% / -20%
• 32 < R <= 100 : +32% / -15%
• R > 100 _____: +25% / -10%

I would like to have that automatic calculation, but if it can not be done i can bear with just reported % value and using calculator to rewrite tolerance.

Thanks

If I understand what you need.

Could you use Result elements to show percentages?
Create the characteristic without tolerances and mask it.
Add 1st Result element, add nominal, then calculate percentages for +/- tolerances. This will show tolerance based on percentage of deviation.
Add 2nd Result element, calculate actual as percentage of nominal for reporting. This will show actual as percentage based on deviation from nominal.

Thanks Rick, but this solution would be more time consuming then select from tolerance norm and using calculator to get right tolerance.

Today i was trying using general tolerance ( ISO 2768 ) but it was giving wrong tolerances.
I got R4 with "m" - so it should be +/- 0.5 but Calypso gave me +/- 0.3 - so i will be implementing own 2768 as norm defines.
