Drafting View Scales

[ChaseWichert]

NX 7.5

I am curious as to why when I put drawing views at 1:18 it shows up in decimal format? Is the software not capable of figuring out that when I type in the ratio 1:18, that I want the scale as 1:18 not 0.056:1.0 I understand that it automatically converts it to decimal in the view menu, but I don't want it to be in decimal. Is this just to tell you that no one in the world will have a 1:18 scale so you should change it?

Try this:
<W@$SH_SHEET_SCALE_NUMERATOR>:<W@$SH_SHEET_SCALE_DENOMINATOR>

Thanks Jerry, but I need the view scales, not the sheet scales, and when I turn the scale label on, I run into the decimal problem. I have several views that are different scales, and it just so happens that the best scale is an odd scale that isn't programmed into NX. Curious as to why something like that would be hard coded in order to limit the use of scales in order to get the fraction style scale to show up. 1:18, is much easier to figure out than 0.056:1.0, and the guys in the shop will look at this and laugh.

Thanks,
Chase

Soap Box time!

Why do you use views that are not 'standard' multipliers.

1:1, 1:2, 1:4, 1:8, 1:16, 1:32, etc for inch drawings.

1:1, 1:2, 1:5, 1:10, 1:20, etc for metric drawings.

Just because the CAD system can do any scale, doesn't mean it is good drafting practice.

Well, that's kind of the point of my post. I am either looking for a work around to get it to 1:18, without just using a note, a simple possibility, or someone to talk me out of using 1:18 scale. 1:18 scale just happens to be not to big or not to small. Also I am trying to learn as much about NX, the stupid things, the great things, the small things, and the large things.

I worked 11 years on the board before being introduced to CAD (35 years ago this year) and trust me, if I had created a 'manual drawing' using a 1:18 scale and even if I had noted it as such in the Drawing's title block, I would have soon been visited by the Chief Draftsman inquiring as to why was I violating the established drafting standards of the company, which were based on recognized International Drafting Standards.

As to why does NX behave as it does, I guess you could say that it was designed so as to at least 'encourage' you to stick to the standards ;-)

Might it be because 1/18 =0.05555555555... etc ( i don't know the correct name for this state where there's no end of the decimals) and thus is rounded into 0.056 ? ( If you don't store the 1/18 but instead 0.0555555.... it is not equal to 1/18.)
- Seems logical.

Your thinking of an 'Irrational' number, like 'π'.

Actually, I think it is just called a "repeating decimal" though there might be a fancier name for them. An irrational number is one that cannot be represented by a ratio of 2 integers. 1/18 is therefore a rational number, but leads to a repeating decimal representation.

At least my post is causing people to think!

And here I always thought 'Pi' was 22/7 ;-)

It is close to 22/7, but it doesn't exist as a fraction.

I WAS BEING FACTIOUS... or was it ironic ;-)

Close enough for the work I do!
