NX 6 - Scale-labels

[Nougatti]

Hi there

Setting the scale of a view to 1:250, the label shows up as 2:500.
Now, I understand that 2:500 = 1:250, but is there a way to customize this so that the label reads 1:250?

Cheers!

The only thing that I can think of is that it's based on some sort of Drafting standard. That being said, I'll make some inquiries and see what I discover.

Thanks, John.
Have you found out anything yet?

Hi Nougatti,
John remarks are true. But in case you still want to go for it.....
(1) Once your view is created along with the scale label.Right click the view and go to PROPERTIES ...In the ATTRIBUTE tab you will find an attribute VWSCALE.....this in your case should have been automatically turned to 2:250 (even though you chose 1:250)
(2) Edit the ratio value to 1:250 and click apply...
you will find that the view scale value has been updated accordingly.

Sorry i have no idea about the mechanism driving the format of value of VWSCALE but this is the only workaround i came across.
One drwaback of using this approach is that you will be required to do the change in the scale text value manually if the view scale changes.
I am working on a better workaround and will send it to you soon.

Thankyou so much, Kapil! I really appreciate it.
I realize 1:250 might be an unusual scale to draft in, but on this powerplant I'm drawing, it really is the most suiting, both space- and detail-wise.

Hi John (Mr Baker)/ Hi Nougatti,
Just when i thought i got it nailed down.....i was taken aback by a surprise....Please find an image attached herewith.I tried co-realting the Scale of the view and the VIEW SCALE text value from the same expression (as shown in image) .Initially it worked good (first time you associate the values to the expression) but when you change the driving expression value ..i was amazed to see that the VWSCALE attribute value is no longer driven by the expression i attached it to earlier and thus the results are same.
John i am not sure if this has something to do with the version i am using (NX8.5) or is it something that needs to be rectified.
Best Regards

I think you will find if you check it out that the so-called 'View Scale' attribute, VWSCALE, is NOT what you think it is. It's not actually driving the SCALE of the view but rather ONLY what the label on the view shows.

Try this, create a 1:2 scale view with the View Scale label toggled ON. Now edit the VWSCALE attribute so that it says '1:1' and note that the label changes to '1:1' but if you check out the view itself, the scale is still .500. Now change the actual view scale by selecting the view, pressing MB3, selecting the 'Edit...' option and change the Scale to 1:4 and hit OK. You will see that the view actually did change AND that the view label now reads '1:4' and if you check the view Properties you will see that the value of VWSCALE is now '1:4'. While it is true that you can CHANGE what the view scale label shows, this value will get overridden when the actual view scale if changed since this attribute ONLY REFLECTS the view scale, but it does NOT CONTROL the view scale. Same thing happens if you used an Expression to 'control' the value of VWSCALE, it will eventually get overridden by the actual view scale value.

Now it is true that you CAN control the actual view scale using an Expression, but this will have no impact whatsoever on how the scale is shown in the VWSCALE attribute and thus in the VIew Scale label. Creating an Expression driven view where the Expression value is 0.004 (i.e. 1/250) will still result in a View Label of '2:500'.

Building on kapmnit123's idea; keep the a, b, and d expressions, but don't mess with the VWSCALE attribute. Instead, change the view style so that the scale is driven by expression d, and show the view scale. Right click on the view scale label and choose Edit View Label; uncheck the View Scale option and check the Customized View Label option. For the custom text enter: SCALE <X0.0@a>:<X0.0@b> and add any custom font formatting as necessary.

Now you can control the scale and the label with expressions. Note that this workaround makes changing the scale a bit "unfriendly" as you will have to switch to modeling to fiddle with the expressions, switch back to drafting, and update the view(s). But, it does allow you to control the label.

If you would like to have access to the Expression dialog while in Drafting, even with a Drawing displayed, simply go to...

Customer Defaults -> Drafting -> Drawing -> General

...and toggled ON the 'Allow Expressions' option, hit OK and restart NX.
