Inconsitent lightweight load behavior
Inconsitent lightweight load behavior
(OP)
Hello NXer's
As part of a battle an ongoing battle to improve the way/speed with which we open assemblies, I have been playing with assemblies using the light weight load option. Now I was lead to believe that unless we refiled our old NX 4 parts, then we would not get the option of using light weight reps, however after some pretty in depth testing, I'm seeing some quite erratic behaviour.
1. Open a large assembly with a mix of data from NX4 and stuff that has been created/modified in NX7.5 and there is a mix of lightweight and exact reps. However on further inspection, there are some parts that are part family members where some components open as exact and others as light weight, even though they have not been refiled or saved since 2008. right clicking on one that is shown as light weight and changing it to exact works, but then it will not allow me to change back to light weight, so it appears that the ANT is not displaying correctly.
2. I open an engine assembly and every part but 2 loads as light weight. I change my selection intent to facet body and try and select the whole assembly and only 50% (ish) selects leaving some very large components in view but still shown as being light weight in the ANT. right click and change these to exact and it opens the rest of the model and all the faceted edges disappear as expected and I can also change back to light weight. The thing I don't understand is why these bodies are not facet bodies and wont select when in light weight mode.
3. I open an assembly that has a large casting in which has not been modified since 2009 which will not have a lightweight rep, but for some reason I can can switch it between light weight and exact without any problem.
It seems as though the behaviour is very inconsistent. Has anyone else noticed the same?
Baffling me. :-?

RE: Inconsitent lightweight load behavior
What I suspect is that some of your older legacy parts may never had proper lightweight (or what we called 'faceted' models back then) data generated in them and until they are saved, either manually after opening or via refile, they will continue to be a cause for some of the inconsistent behavior that you're seeing.

Any thoughts on this, John?

RE: Inconsitent lightweight load behavior
We have 10 sites around the world.
A part can only be owned on one site.
The part has to be refiled on the site where it is owned.
Many of our parts will be used all over the differnt sites which means there are many copies of the part.
These copies can not be refiled, which means lots of time filtering parts.
Therefore we have to identify where each part is owned and refile locally on that site.
All refiled parts will then sync overnight back to the central server where all released parts are copied to.
If the part/s have been imported for use on other sites, then once they have sync'd back to the central server, they will then also be re-exported to those sites.
This will mean masses of data being moved around on a night time.
we have around 750,000 parts to refile.
The logistics are just beyond comprehension.
Nobodies fault, nothing we can do, it's just the way it is, but it has meant that it will be a very long time before we can get full benefit from the light weight reps.
We can't even get each division to revise their parts as suppliers will use this as an opportunity to requote and raise their prices.
Dooooom!!!!
