question to Nx mold designers

(OP)
I have to prepare a product for mold tool design.
The product consists of 3742 sewed faces. After some face operations ( extract region, trim extend, trim sheet - mold design preparation -) the (NX4) System slows down, the peformance gets bad. Are the some tipps to handle this problems.

RE: question to Nx mold designers

Don't Panic!

Try linking the body and then breaking the link, you're effectively ditching the parameters and may save some grunt for having done so. Unlike removing parameters breaking the link can be reversed, and it will make you wait when you need to do it, but in between times you may enjoy fuller use of your system's memory. Also this doesn't work in all cases I can't vouch for the contents of your geometry but it is quite likely worth a try since nothing else that I know of makes much difference.

The only other thing you could do is to talk to other mold wizard users about how they manage automatic updates with the other linked geometry that it creates. I believe dialling back on these can be appropriate from time to time, because you can be required to make changes through the course of several steps before you really need to fully update the model.

RE: question to Nx mold designers

Whenever I have a sewn object, I usually remove the parameters.  If I need to modify a face and have to do surfacing,  I can always extract the face/region, do the change, sew the surfaces, then remove parameters again.

Check the file size when an object is sewn together and when it does not have parameters.

RE: question to Nx mold designers

I just finished a part with 8,000 surfaces, the core inserts were particularly hard on the system.  Updates would take tens of minuets, rendering and rotating the display were hideous.  I could not break any links or remove associativity, but I needed to get the cores outta here!

1) Make a new component, core_light, and wave linked the core body into this new part.  
2) Set this part to lightweight/facet reference set.
3) Set the original core to empty reference set and CLOSE it

Now, the core is closed and will not update, but you have a lightweight rep of it on screen.  When you need to change something, make all your changes in advance and then open the core fully.  Take a coffe break.  

With the empty reference set, the cores will not open when you open the assembly.  Also, the moldwizard standard components are messed up and do not allow the lightweight reference set, so this method gets around that limitation.
