Hi,
the pattern face command present into instance feature is the same present into synchronous modeling (history mode) ?

Thank you

I'm sorry but I don't understand your question.

Hi hudson888,
you have right, my question is not so clear.
When I model a part, always I look for the best practice.
I want to model in a way that NX7 need less time to regenerate the part structure and if my colleague need to revision the part, less time to understand how it was modeled.

About my question, I know that the synchronous modeling command in history mode are very fast.
In this toolbar exist the 'Pattern face'.
The same name command is present under the 'Instance feature' command.
If they are equal about performance...the question is closed, but if they are different....can I use 'Pattern face' command of ST toolbar in sheet metal or modeling environment for enhance the regeneration part performance ?

They can do the same thing, but if you have a feature it is best to instance the feature.
I feel that it is easier for the person decipering the model to see the specific feature repeated other than faces repeated - there are also some added benefits to doing an instance; such as blending, in the way that you are able to pick one of the features in the instance and all of the others will be blended.

To answer the original question; there is NO difference between the 'Pattern Face' command that you can access from the Instance Feature dialog or the one that you can access from the Synchronous Modeling toolbar. It is simply two ways to get to the same function.

Now as for your 'reference' to history (and history free) modeling, please keep in mind that while this option appears on the Synchronous Modeling toolbar however you decide to set it, it effects ALL modeling commands, NOT just those on that toolbar.

Cubalibre00,

I prefer to use pattern face when I can because it seems a little quicker and more elegant as a solution. It won't work in all situations and then instance feature is probably the next best option.

In NX-7.5 it may be the case that the way hole arrays as feature instances can be used to generate component arrays has been enhanced. I remember that this was mooted, but whether at NX-7.5 or NX-8 I am as yet unsure. For earlier versions however the case is clear that using rectangular or circular hole arrays where you want to install a range of similar fasteners has that slight advantage.

uwam2ie,

Attached is a simple file in NX-5. There are two examples yours which doesn't work but has a simple alternative solution, and one with topology that does work. They're separated by layers. You may come to your own conclusions as to how detrimental such a failure to perform the patterning operation you suggested actually is, but I think I would be at a loss to invent a situation where this solution or a similar work around was more than a minor inconvenience.


Best Regards

The only 'Patterning' enhancements which made NX 7.5 were the ones added to the Sketcher. A more general set of 'Patterning' enhancements, across a broader expanse of NX, is being planned for release starting with NX 8.0.

thank you Hudson*** and John,
@John - the biggest approach in ST over direct modeling from nx4 for me was the preview. I can see the failture. This is missing in pattern face ( and some other commands).
thx

What version of NX are you running? Preview has been fully supported in Pattern Face since NX 6.0 (and even in NX 5.0 you could manually ask to see a preview before committing to the operation).

As for your 'Mirror Face' question, this works fine, but NOT using the Pattern/Mirror Face, but rather the explicit Mirror Face command, which was added to ST in NX 6.0.

ok John, thanks
but as you see mirroring in pattern face doesn't work.
I looking for (what are)the limits of pattern face -

I wouldn't lose any sleep over the 'limits' of Pattern Face since its almost certain going to get a major overhaul in NX 8.0, and it's very possible that the 'mirror' option may not even be there after that. After all, if you look at Pattern Face, it's virtually unchanged from when it was added as an option under Array Feature. It was moved to (actually copied) the Synchronous toolbar simply because it was better suited there, but still far from being a true Synchronous Modeling-like function whereas the new Mirror Face function does have all the trappings that we've come to expect with Synchronous functions.
