Removing the secondary units tolerence in NX Drafting

Removing the secondary units tolerence in NX Drafting

Removing the secondary units tolerence in NX Drafting

(OP)
To the Quick:

1.   I want to be able to shut off the metric tolerancing and simply put the metric numeric value for reference but leave the English tolerance.

2.   Is there anyway to have NX convert the rounded value directly to Metric instead of using the more accurate value it took from the model?

3.   I'm also open to suggestions and best practices.



Background Info:

This past week I've been getting hit up by our German counterparts.  In NX we are using Dual Dimensioning where English is primary.

I'll start with the secondary issue.  They've noticed that the English and metric are not rounding to be the clean 25.4" as they expect.  eg: 1.35 = [34.2] as apposed to in NX  1.35 = [34.3] by using a calculator.  I understand NX is taking the actual value and rounding that (as it should).  I really don't know what to tell them about this other than we may start using 3 decimal places on both... i don't know.  So... To make people happy...  Is there anyway to have NX convert the rounded value directly to Metric instead of using the more accurate value it took from the model?

The issue that bothers me the most is that our plant still uses English (Please don't shoot me... its not something that is going to change soon and I don't want to argue that point.)  So everything we have is tooled in English and gets bought off using English.  However, in certain cases, the metric value actually comes out tighter.  eg: +/- 0.06" = [1.5] reversed however [1.5] = 0.591.  Splitting hairs?  Yeah.  But people love to split hairs.  Can't change that either.  I want to be able to shut off the metric tolerancing and simply put the metric numeric value for reference. (probably violates ANSI Y1484.536ZZZ 2055)

I'm also open to suggestions and best practices.

If it violates the 'standards' then there's probably no built-in means to do this.

So still... what do yu all do?

RE: Removing the secondary units tolerence in NX Drafting

We follow the standards and let the system round things off as it wants to. :)
Then we tell management that the system is working as designed and we need to adjust our attitude to let the system work for us instead of fighting it. If we have to change procedures, then we will document why and what impact is involved, make the change and move on.

When I started at one company many years ago, they used metric dimensioning with trailing zeros. At the time they started, UG did not have a setting for that. When I set up the new version and turned on suppress trailing zeros, it caused all sorts of trouble. Tolerances now had to be exlicitly called out since the title block defaults changed things. We held a meeting, explained to engineering and manufacturing what happened and why and then agreed to change all revised drawings going forward. Our drawings had a notation on them saying that the drawing was done in accordance with ASME Y14.5-1982 (at that time).
