Assembly Slow Down Causes
Assembly Slow Down Causes
(OP)
Would anyone have insight into the workings of an NX assembly in regards to what may slow down the model response in regards to interacting with the model (rotation, zooming, etc.)
I have a very large 10,000+ part assembly where I only load certain sections of the model depending on where I'm working in the model. If I load models closer to the top of the assembly tree things are fine in regards to model interaction, but when I load a single part much lower in the assembly tree, which means the assemblies along the line will come into play, though without loading anything else in those assemblies into memory the model comes to a crawl especially in selection and zooming.
It doesn't seem to be model specific it just happens when I have a large assembly and load items at deeper levels in the model. The problem is I would expect that loading single items shouldn't slow the model down but when the items are deeper in the assembly tree something else must come into play within the assembly navigator when loading 1 or 2 items that are at deeper levels into the assembly tree. Does anyone have any insight into what NX is loading even if I only choose 1 item at the deeper levels of the assembly tree? There's seems to be a much longer lag time when trying to rotate or zoom the model after any of those deeper leveled items are loaded. When checking the ram pull only 1 GB is used for the model on a 32 GB machine, but the model is still slow to respond.
Using NX 9.
Thanks!

Here's my load options settings:
Here's an image of the parts loaded in the assembly context. The parts shown are 4 levels down from the top assembly.
Thanks!

What I suspect is happening is that even though you've opened the Assembly with the Lightweight option toggled ON, those older parts do NOT have any Lightweight data so it's having to create those representations on-the-fly and since they are never being saved in NX 9.0 format, they have to repeat this process every time these older files are opened.
Anyway, this 'refile' really needs to be done before you go any further in terms of looking for some help with this performance issue.

For the refile utility can this be done on a server side with all the files stored in Teamcenter?
I've been asking IT to also maybe run Part Cleanup on all the file associated with this program to reduce some issues we have with the older files, but I don't know if they can do that from the server side either.
Thanks!

If I can get them to do the refile and/or part cleanup I'll post an update for a complete story on the post.
Thanks again!
