dimension display

[boldfish]

In NX4 I'm having difficulty with a displayed dimension.

I have a dimension that is exactly .21418. When displayed as a two decimal dimension on the drawing, it shows as .22 until the view is updated.

I don't know how to explain this behavoir and it now makes me question all the dims on all our drawings. How can I ensure the views are updated without manually doing this?

Is the rounding convention in NX4 the same as that used by excel?

 

[ewh]

It is per a national standard, though I'm not sure which one. Do a search in HELP for "decimal rounding standard" and one of the results is an explanation of how drafting handles it.

Sorry, my post didn't really address your problem. I don't have an answer other than updating the views when opening the drawing.

ewh,
Are you saying that views (automatically) update when a drawing is opened, or to (manually) update the views after opening a drawing?

Whether views automatically update or not depend on your settings. I don't recommend auto updates for drawings of assemblies, but for individual parts it is probably ok. When you first open a drawing for reference or plotting you need to make sure the views are up to date. An icon will show up next to views that are out of date (in the navigator). You can use the right click menu to update individual views, sheets, or the entire drawing.

cowski,
That is the item at issue:
There was no indication that the view was out of date. No icon in the navigator nor were the dimensions greyed as I have seen in the past.

Actually, I believe the view to be not out of date. It just seems that updating the view corrected the dimension.

I still am no closer to knowing what is going on with this drawing. And I am still questioning the correctness of all our dimensioned drawings. For now, I have suggested that all drawings of critical importance be scrutinized and thoroughly updated.

Luckily in this instance, the dimensions are not critical; but there could easily be a drawing that this would make a huge impact upon furnished parts.

I have asked the question of one of our outside UG trainers if he has ever seen this happen. I will let you know what I find.

 

[ewh]

Another reason for MBD (though I agree that this should not happen with such high cost software).

Do you by any chance have the extracted edges option on for that view? If the original model is changed the drawing may indcate that it is out-of-date, but individual views probably will not since technically they are NOT out-of-date. The data, the extracted edges, are alwasy seen as up-to-date, which is the whole purpose of using this option in first place so that NOTHING on the drawing updates until the user triggers it. It sort of like having my cake and eating to, in the sense that my drawings will ALWAYS look correct and NOT REQUIRE an upate inorder to LOOK correct yet still have it associatively linked to a model/assembly. In fact, this is usually only recommend when dealing with large assemblies so that a drawing stays usable longer, even if changes are being made a some lower level of the assembly as this will prevent any partial updates to occur until the user is ready for them. Of course, if you were working in a Teamcenter environment, there are other ways of controlling this (as their are in in native with search paths and revision rules) but for most native users with a single set of models, this can be used to provide more efficiency when working with complex drawing of large assemblies, but there are some downsides and that is that the NEED to do an update is not as readily noticed and therefore you have to force updates, but at least you now have total control over when you feel that you NEED to perform them,

Anyway, double click on your view and when the View Style dialog comes up go to the General tab and check the status of the Extracted Edges option (at the bottom of the panel).
