Model State “All Content Center Suppressed”

[RajSchmidt]

When opening legacy assemblies in Inventor 2022 all user defined LoD are converted to Model States, which is fine. The default LoD, however, are deleted. I think that at least the LoD “All Content Center Suppressed” was used quite often.

In 2022, if I want to define a Model State without all CC parts, it becomes quite cumbersome. I have to pick the parts manually or use the browser search.

I would like to have a pre-defined Model State “All Content Center Suppressed”.

Hi Raj

Thanks for the feedback,  hope you have seen that through help documentation. Since the behavior change, suppressed components will not participate in BOM, we provide an option when open assembly file, refer to below snapshot. Considering current Design View includes views for 3D annotation and user-defined views, we decided not to list all CC invisible under the node of view representation.

From Inventor 2021, we have optimized Inventor document loading behavior to avoid loading unnecessary invisible components. One purpose to suppress CC components in the past is to reduce memory consumption, you can achieve it through the Design View. If you really want to exclude CC components in BOM, it still works to copy the view to Model states, and vice versa.

Hi Jingyi,

thank you for your response!

Yes, I can open an assembly with all CC parts hidden. But to get this into a Model State looks rather cumbersome to me. I have to

• open the file with the correct options
• the current Design View might be “Master” which I cannot copy into a Model State
• so I have to copy this into a temporary Design View
• this I can finally copy into a Model State

If I miss any step or switch to another Design View in between, I will have to start again.

And it gets even more complicated when I use Vault. When I open directly from the Vault Explorer (as many folks do) I don’t have access to Inventor’s load options.

Hi Raj

For your first described workflow, I'm not sure whether you really need a Model States to suppress all CC components, remember all of them will be excluded in the BOM.  Based on our customer research, we found "CC suppressed" LOD usage is pretty low, in most cases, customers expect to suppress them for performance, not for BOM. As said, we optimized the Design View loading behavior, it should not be a big concern. 

For the Vault workflow, it would be better to use Vault-addin and open from Vault. If you try to open directly from Vault Explorer, you may open the Master or Last active LOD in Inventor 2021, there is no file open option to select "All CC suppressed" as default.  In Inventor 2022, if you always want to hide CC components, the alternative solution is the File open option to hide CC components in Design view.

Hi Jingyi,

I agree that we have to think about the implications of suppressed parts for the BOM. I think we all still have to find out all the possibilities (and snags) of this new tool.

However, many of our customers still rely on suppressing parts to improve the performance, especially if they have to handle huge assemblies. And again, in these fields BOMs actually become somewhat less important. If I design a chemical plant, I don’t count nuts & bolts. They are just shipped in bulk to the site.

Anyway, it would just be nice to have a quick way to filter them out and store this setting.

As for the Vault workflow: Yes, using the AddIn should be the preferred and safe method. But I daresay that 90% of all users are just lazy and double-click.

Hi Jingyi, I think it is very useful to add a new option in the view representations in addition to Main and Default that allows you to hide CC Files. This is in addition to the current option in opening assemblies.

We've been working with Inventor since time immemorial. Since version 2009, there is a unique opportunity to perform suppression of all details from the Content Center library (System-defined Level of Detail representations). In version 2022, this feature was removed, which greatly complicates the work when the model contains a large number of elements from the library. Could you return this functionality and expand its work by automatically suppressing all items that have the status of purchased items in future versions and updates?

Hi, this topic has already begun to be developed on the Russian forum, there are more than 500 views.

https://forums.autodesk.com/t5/inventor-i-promyshlennoe/izmeneniya-v-fayle-sborki-2022-quot-uroven-d...

I have been working in this program for over 10 years.
And now I have difficulties in connection with this change.
Now, it is difficult for me to make changes to previously made projects and new ones, since before the entire library could be disabled in assemblies of any level with just one click, but now this is impossible.
And most importantly, these are drawings, since there have been and are many drawings with assemblies where library components are suppressed.
How do I make changes to these drawings now?
Now it takes a lot of time, but in our common business, time is money.
It takes much more time to correct the drawings after correcting the models.

Hi,

the All Content Center Suppressed level of detail has many utilities:
- Inventor 2022 has a performance boost, but not enough to handle complex assemblies with thousands of Content Center parts
- Opening the assembly with the "Hide content center components" design view forces me to close and reopen the assembly.
- Imagine having to export the file in step or pdf3d without content center parts, the detail level All Content Center Suppressed is very useful.
- Model state affects the BOM, that's right; and often you want to create a BOM without a Content Center to execute production orders. Later a BOM only content center for the warehouse.

The arbitrary choice of eliminating this LOD, with no alternatives, is not a good thing.

Best regards,

Bruno Milano.

Hi,

sorry, i forgot a point.
If I have drawings with views related to LOD the All Content Center Suppressed, will these be ruined?

Model State “All Content Center Suppressed

Why is this feature not available in Inventor 2022? please i want your inventor 2023 feature

Many thanks for posting the idea to us, and tracked as [INVGEN-59474].

@RajSchmidt @ersin.bilgin @bmilano @vasiliy2006 @pbVE3M6 ,

Would like to get more details about the CC parts here. Do we want to get all the CC parts suppressed/invisible within the entire assembly? Or we can also get the CC parts within the active assembly level suppressed/invisible?  For the "All CC parts suppressed" LOD in the legacy behavior, we will suppress all the CC parts within the entire assembly.

[a.chinellato]

Hi Yijiang.Cai, After months of using the model state I think that the commands to be introduced could be two.

One for view representations to turn off all content center components on all assembly levels (think of a default view present in all assemblies).

The other for the model state where all the content center are suppressed, always on all levels of the assembly, and the components are also removed from the BOM. 

[RajSchmidt]

Hello @Yijiang.Cai, I completely second what @a.chinellato has been saying. I think it is important to grab (almost) all CC parts in one go. Parts you should not consider, though, are frame members, channels, I-beams, etc.

[Edward.Cox8EPVC]

Hi All

The content center parts don't really scare me.

But I do now have a huge problem as the option to open all Components Supressed is now gone, I have plant layouts with thousands of parts that cannot be opened in Master. So I open with all components supressed then unsurpress what is needed.

I really need a solution quickly and I know I'm not alone in this, all people that work with large models use this.

I currently open a LOD (model state) of something I don't want to use and then shuffle to what I do want. Just silly.

Thank

Eddy

Hello, as I wrote earlier, they changed what was in the program for more than 10 years.
And now there are great difficulties with working with old projects.
Yes, and with new ones, too, you have to relearn.
Give back what was taken from us. )))))))))
I use "СС" suppression when working with Responsiveness in an assembly.

[josef_kostecký]

In model state in the 2022 version I expected great performance savings by suppressing the content center. We work with large assemblies (50 thousand components).

We have introduced two model states:
Simple - suppress content center at current level + "Simple" state setting in subassemblies (suppressed content center)
Simple DRW - enable content center at current level + "Simple" state in subassemblies (suppressed content center)
"Simple" model state for montage employees, that has weak hardware and only needs to view
"Simple DRW" model state for the needs of lightening the view in the drawing, where it is not necessary to display the content center in subassemblies.

Once deployed for use with Vault Workgroup, subassemblies are repeatedly published and updated. It is very unfriendly and we are not able to release the data to production in the current state (update mass, model states,...). In the release process, you need to update the currently approved subassembly when you open the parent assembly. And all the time.

Simplifying big data just by making the content center invisible is not as effective as suppressing components.

Suppression also shuts down components from BOM, which is unwanted when using state models, but I understand the idea.

It would be possible, as we read from the posts above, to create model states by default that:
* Suppresses components (CC)
* does not turn off components from BOM (same functionality as LOD)
* no excel table created (I don't want to create an iAssembly)

[Yijiang.Cai]

Many thanks for you all providing the quick feedback, and it is really helpful.

[jingyi.liu]

@Edward.Cox8EPVC 
I would suggest you use the file open option, select "Nothing visible" from Design View dropdown list. In your case, changing component visibility rather than suppressing components could achieve equivalent effects.

@josef_kostecký 
In legacy LOD workflow, if you have made changes to your design, it will cause mass properties to update no matter it is master or non-master LOD. To update mass, you need to load Master LOD to compute indeed. 
The technical logic of Model States is different from legacy LOD, one intention of Model States is to address LOD usability issues. Searching LOD on this Inventor forum, you will see lots of requests to fix LOD issues.
With Model State from Inventor 2022, the alternative solution for your workflow should be Design View, using it to manage the visibility of Content Center Components, it's also helpful to improve graphics performance, and drawing performance. We're aware of the importance to streamline the workflow to turn off CC component visibility.   

Thanks,

Jingyi

Hi, it's important to me that I can suppress "CC" while working with the assembly, and not before opening it. Because you may need it at any time.
