Advances weight management while using WAVE=
Advances weight management while using WAVE=
(OP)
Greetings all!
I'm trying to understand the weight management if WAVE linking is used. I attached a simple assembly for illustration purposes. There I put together two simple parts, created WAVE links of the bodies and subtracted some material from them. Then I created SOL reference set and put in into the advanced weight management as a reference set for weight calculation. But weight of the part is still calculated using both linked bodies and components weight (see the screenshot). Of course, in the upper level assembly, where I put two subassemblies, the weight is also grossly incorrect. Is there a way around? Perhaps the answer is in the components groups? I couldn't work it out as of yet...

You have done your WAVE link bodies directly on the 'TOP assembly Level'.
That may be the reason for the wrong values.

*****With NX6******
While using wave link, use link bodies and and change the layer of assembled bodies to non-working layer. You can set density for the "linked bodies" from material table or "Edit->Feature-> Solid density"
I hope same option is available in NX8
Thanks,

WAVE is a method of creating associative copies of models I will give two examples.
A symetrical component.
If you have two parts lets say a left and a right hand, you don't want to have to model 2 parts. You can create a mirror body WAVE link about a datum plane. This will create an associative copy of the main model however in the part navigator, there will only be one feature - the linked body. When any changes are made to the parent part, these will then update in the WAVE linked body to reduce the time to update the part.
A casting that has machined faces.
Take a casting that requires some machining for example. You can have 2 totally different part numbers. firstly part number 1. This will be a model of the casting in its raw form i.e. as it comes out of the mold. we can then create a new part, part number 2. we add part number 1 in to part number 2 to create a small assembly and then create a WAVE linked body, this is basically an associative copy of part number 1. we can then add extra features to the WAVE linked body such as machining detail that would be done to the blank casting. You would now have 2 models. one of the blank casting, and another of hte machined casting. Any changes that are made to part number 1 will propogate through to part number 2.

I finally got round to posting a reply.
Thanks for the explanations and video! I know quite well what is WAVE and how it can be utilised. I only got rather suprised that there is no way to exclude the mass of the assembly components from the calculation. Suppression has one shortcoming - is a component is suppressed, wave link won't update. That sort of defeats the idea of WAVE-linking.
There is an ability to manipulate component groups and use such group as a reference for mass calculation. Maybe there is a way to create component group contatining no components and thus exlude them from mass calculation? But I did not find a way to creat such group.
