Annotation size relative to drawing scale

[Ritchie]

Is it possible to set the annotation size relative to the drawing scale? On a larger scale drawing (for instance a scale 1:1 detail) I would like the annotation size to be bigger than on a smaller scale drawing. Is there a scale factor that scales all of the annotation settings uniformly?

I'm using NX 8.5 by the way...

With some journaling or NX open programming this can be done I think.

However...do you really want to do this? If you want your drawings to follow normalized standards then you are bound to the size you want to use on your drawings.

The range of nominal sizes is specified as follows:
1,8 mm; 2,5 mm; 3,5 mm; 5 mm; 7 mm; 10 mm; 14 mm; 20 mm
The multiple of V² in the range of heights for lettering is derived from the standardized progression of dimensions for paper sizes (see ISO 216). The line widths shall be in accordance with ISO 128-20 and the same line width shall be used for both upper-case and lower-case letters.

You would be better off changing the size of your drawing sheet than messing with character heights.

All drawing sheets will have to be in A4, so no changing of the size allowed here. I guess there is no other option than changing the annotation size manually, then?

It can be done.



The annotation preferences size cannot directly reference to an expression or attribute so it would have to be done through some coding like Journal or NX open.
With Journaling or NX open you can create a tool which can retrieve the scale from a view or you can create an expression which can be read.
Then the tool can set a derived value in your annotation preferences..

The avoid strange lettering sizes like 3.1256 you would need to build in a round of in the code. or at least let it pick from a set range of heights according to ISO.

Thanks for your answer. I'm not familiar with journaling or NX open so I guess I just stick to manually editing the annotations. I just wanted to know if there was a "simple" way but apparently there is not...

Are these dimensions that you're creating first THEN going back and manually editing? If so, set your text preferences once before creating dimensions. Record a macro to change the text size - you can map out the macro to an icon. Write several for more than one text size.
