Double weight
Double weight
(OP)
Hi,
I set steel material to a component.
I insert this component in the assembly.
I create a wave body link.
I add feature.
I set steel material to the body.
I saved the assembly and now I see double weight.
Why ?
I attach a picture to understand.
Thank you

RE: Double weight
It appears that you have set steel to the body twice, once in the assembly, and once at the component level.
I don't think you need to set it at the assembly level, it will inherit the steel properties from the component.
RE: Double weight
I've tried now your suggestion and saved the assembly, but the resul is alwais the same 2 x weight component.
Thank you..
RE: Double weight
If you wave linked the body and you have it as a component, you now have 2 bodies in the assembly (reference set doesn't matter). Unless I am misunderstanding something?
RE: Double weight
the purpose of the linked body is because I need to cut the molded part.
Have you any suggestion to perform the right weight calculation in the assembly navigator ?
If the weight column in the assembly navigator is non real, and if I insert 123 flange, the weight is absolutely incorrect.
Thank you...
RE: Double weight
Or you could go back and assign, at the assembly level, density of 0.0 to the extra body.

RE: Double weight
when you look at Cubalibre00 attached picture,
we can see that he is using some colums in the ant for attributes or additional information connected with the components. Here is some thing like an ER :
I think it would be usefull to filter the columns, as a view.
I have serveral views in the ant where different visible columns are stored - and switch between the different Ant views
Hope you can follow me, thx

RE: Double weight
thank you for your explication.
Promotion was disabled in our customer default, because the support told us that promotion was discontinued and replaced by wave link.
When a cast part need to be worked, support and the courses teach to use wave geometry link body, now you suggest to use promotion.
It clear that I want that NX calculate the weight correctly, so can you explain me when use promotion and when use wave geometry link body ?
Regards....
RE: Double weight
The topic comes up from time to time on the forums so you can search here for more detailed earlier discussions. In general if anything is or can be agreed then it would be that promotions work best for things like weldments and occasionally castings. Most people these days do use and prefer wave links because they're more sophisticated, and the devil is in the detail when it comes to deciding what best reflects your company system and work flow.
In the context of this recent discussion wave links don't always double you're mass calculations depending on where you link to and from. One of the more flexible aspects of the system is that you can wave link from anywhere within a given assembly to anywhere else in that assembly. Like anything flexible anarchy is also a possibility. Promotions on the other hand work on the basis that the solid is promoted from a component that lives directly underneath the part which will contain the resulting promotion.

RE: Double weight
I'm sorry for the question, I understand that in this forum was treat very often.
I will search in the forum to understand better where and when use them, maybe discussions from users and their experience is a lot better then support and courses.
Thank you again..

A technique I often use but not necessarily for this reason. Remember there's more than one way to skin a cat, especially when it come to NX!

RE: Double weight
Ahh yes! One of the first things I tell a class of new users on day one and then repeat with monotonous regulartiy throughout the 5 day course "With NX there are many ways to skin a cat"
@ Cubalibre00
Depending on how you do business, has a big impact on how you use WAVE. If you use Teamcenter to generate your parts lists, then WAVE is ideal, it will afford you great flexiblity as to how your parts are bought/procured. Take a simple casting for example, we have 2 part numbers. 1 for the cast blank/pattern and one for the finished machined part. by using WAVE, you can create the master part (or blank) then create a new seperate part number for the machining. Add the blank to the new part number and create the WAVE link. This creates a nice parts list that details both parts (if that is what you want of course)
Now, use the method I detailed before to suppress the blank, this will take care of all you weight doubling issues and Teamcenter will also create a parts list detailing the top level part number of the machining and the component part number of the blank. This indicates to purchasing that if you are doing machining in house, then they will need to procure the blank part part number. If you buy the machined part in completely finished, then again you have a number of options, either turn the blank to reference only in NX so that it doesn't feature on a parts list and purchasing only then buy the finished part, but ideally, leave it up to them to decide how they want to buy the part, we personally use the parts list method for all WAVE linked or multi-process parts such as W/A's that have secondry machining operation.
The point I'm getting at, is that if you use WAVE linking, you can use the component suppression very effectively to ensure that mass is always correct. We use masses of WAVE linked parts, and also use other systems to give us cost reports amongst which is Cost/kg for castings so it is imperative that our mass is correct and not doubled up. We also link this mass to the drawing border, and in the past we had a problem where a supplier in the far east had quoted us delivery costs for a casting based on the mass that was displayed in the drawing border which in this case was double. NOT GOOD! So after years of messing around with advanced weight management, reference sets, manually altering density, etc, etc, we discovered component suppression and it has been nothing short of a silver bullet to cure ALL our mass problems associated with the doubling up of WAVE linked parts.

RE: Double weight
Glad you chimed in with that you offered a similar explanation earlier in another thread and it illustrates well how different systems influence why you'd need to have more than one way to do things.
For some reason my old instructor always used to embellish the expression by say "there's more ways to kill a cat than by choking it with whipped cream"! Who thinks these things up?

RE: Double weight
I use TeamCenter.
I think that promote is the best solution now.
I don't have weight problem, I have correct part list, also in Structure Manager.
I don't have reference set problem.

RE: Double weight
if I suppress the part, the part list result incorrect.
If I set to zero the density to the linked body, I lose the correct weight because cut operation are not evaluated.

RE: Double weight
I have only one other thought that may help.
Some of this may or may not relate to where you're linking to and from, since you can pretty much wave link from anywhere in the assembly. Maybe we've fallen into assuming that the component being wave linked from is loaded directly into that where the link is being made, as per Simon's example. In that case I believe it would work as he described. Other scenarios may involve wanting to suppress the component at the specific level where the link is being made but not at other levels. If your assembly structure is different or more complex than the one which Simon has shown then perhaps you really ought to send in similar images for us to comment on in order that we may identify and help you correct any such errors. Otherwise we're only guessing as to why you seem to be struggling labouring under the suspicion that it could be any number of things.
Mind you it might just be that case that you arrive at the classic example where it is simpler to use promotions. It is usually something like a weldment!

RE: Double weight
it's true....Structure Manager the new PSE name in TeamCenter show the part if is suppressed, but I use the part list in the specification and the part list doesn't show the part suppressed.
Thank you...
