Why is NX sooo incredibly slow, especially when working in drafting. It is always updating, updating and updating. It drives me crazy!!

I use NX7.5
HP Z600 Intel Xeon E5520 2.27GHz Dual
9GB Memory
Windows 7, 64-bit

What graphics card is in your machine?

How many views are on your drawing sheet?
Set the system to manual updates, make your changes then turn auto update back on and cycle the sheets.

I have a NVIDIA Quadro FX 3800 video card.

I work with 2 views and 1 sheet.

To manual will help a bit maybe but mostly when you change anything you want to see the result.

Here's something you should check; go to...

Customer Defaults -> Drafting -> View -> Threads

...and check to see if the 'True Hidden Line' option is toggled ON. If so, toggle it OFF and hit OK.

Now since it was ON, this means that all of your Drawings were probably created with this option ON as well, so you will need to open your Drawings and select your views (you can select ALL the views at once and change all of them), press MB3, select 'Style', open the 'Threads' tab and toggle OFF the 'Render True Hidden Line' option. This will improve the performance of updating Drawing views.

I've checked it and it was indeed turned on.
I toggled it of but it doesn't seem to help a lot.
But thanks anyway.

We have workstation HP Z200. I have noticed, that it is taking much more time to update view in drafting, if setting in view style for interfering solids is set to "yes, with interference curves". So try set this option to "none".

Michel,

Is this an assembly you created in a previous version of NX?
If yes, how was the performance?
You can also check your network settings to see if there is a bottleneck in getting the data from your network.

This option is already set to "none".

I created it in an earlier version it then it was also slow.
I don't know how and what to check about the network settings. But isn't it right that once it is loaded in your pc's ram it doesn't use the network anymore?

in some cases ( give it a try )it is good to deactivate hypertheating in the system bios

I have reported this both in this forum and with IRs to GTAC and still no root cause that can fix it. I have performed testing of similar model/drawing complexity with other CAD systems and always get the same result. Whenever an NX view update takes minutes, other systems can update in seconds, whenever NX view updates take hours, other systems can do in minutes, and so on. Is your geometry all native NX or is some of it imported? One thing that was causing NX to hang on view update in a recent case of mine is that the users model contained some imported geometery with geometry errors. You might try running examine geometry to make sure you don't hvae any serious errors (the ones in the middle of the list in the examine geometry dialog) and if you have errors clean them up to see if that helps.

Ok you confirm my experiences that drawings of fairly big assemblies are always very slow. My experiences with other CAD systems were a lot better too with drawings.
The geometry does not contain any imported geometry.
I've examined the geometry and did not found any errors. This is what it says:

Tiny objects found = 878
Misaligned objects = 60
Face - face inconsistency
Please replace incorrect geometry (many times)
Number of boundaries found = 32
Number of faces with possible spikes/cuts = 6
Number of unsmooth edges found = 190209

But I have no idea if some of these numbers are bad and how to get rid of them. By clean part maybe?

"drawings of fairly big assemblies are always very slow". It's time to tune NX I think:)
The list shows enough errors to explain the bad update times.
Are you sure all components are native NX? Maybe some of them contain imported STEP or, worse, imported IGES geometry.
In my experience, IGES is a notoriously geometry failure.

Try setting the angle and distance tolerance in modelling preferences to a lower value. Hope this helps.

@Michel
look into Help -> Design -> Dafting -Assembly->
there are some tipps how to deal with large assebly drawings.
For my large assemblys it was very helpful to use the extracted edges in a view and turn automatic view updates off by default,
and thre is a lot more you can do. For your imported gemometry optimization - remove useless segmetation - Modeling -> insert->combine->join face first option.

It may be you upgrades from Microsoft are corrupted. IT is working on mine now. .NET Framework files are propagating like rabbits.

Has any one any experience with running NX on one of the BOXX systems that usually tests at the top in NX performance? The last comparison I saw was in Desktop Engineering with a BOXX system configured at about a $6000 price point. Sorry I don't have the specific specs readily available.



I am using 7.5.2.5 NATIVE on Dell with windows XP OS
