Can this be seen as a Large Assemly for Inventor?

[bradeneuropeArthur]

Hi,

Can the following assembly been seen as a large Assembly for inventor.

We have some trouble with handling the assembly:

• Opening; Rotating and Editing of the Assembly is very slow.
• the related Drawing is very slow with opening and updating.

Total occurrences in active document: 26418

Open documents in session: 1501

Also with the "Express Mode" enabled the assembly is very slow!

And there is no change in the numbers with "Express Mode" Enabled or not.

Our configuration:

• Our application option are set to "Performance".
• DirectX Version: 12.0
  DDI Version: 12
  DDI Version Number: c
  DxDiag WHQL Level: 0
  Driver Signed Valid: True
  Driver Signed: True
  Manufacturer: NVIDIA
  Chip Type: Quadro P3000
  DAC Type: Integrated RAMDAC
  Revision: Unknown
  Graphics HW Memory: 14254 MB
  Display Mode: 1920 x 1200 (32 bit) (59Hz)
• Graphics driver file: 
  Driver file version: 21.21.0013.7711
  Driver Date: 17-Mar-17 02:00:00
  WHQL Level: 1

Is this a large assembly for our system?

Please give me your comments.

@bradeneuropeArthur 

Express mode doesn't change the number of components in memory.   Express mode loads them differently in memory (kind of like a light version of the components).   Then when you do certain operations it then loads the full mode of that component behind the scenes.  Has the file been save in Express mode and re-opened.

Yes this could be considered a large assembly.

What is your operating system?

What do you have here? 

Or here   or even here under the drawing document settings

Perhaps you will want to review my class handout for AU on Boosting Inventor Performance

Thanks for the respond.

Same application setting as you have.

Operating System:   64-bit Microsoft Windows 10 Pro (Build 9200)
Language:    English
System Manufacturer:   Dell Inc.
System Model:    Precision 7720
BIOS:     1.13.0
Processor:    Intel(R) Core(TM) i7-7820HQ CPU @ 2.90GHz (1 processor, 4 physical cores, 8 logical cores)

Hi @bradeneuropeArthur 

Have you taken a look at the Large Assembly Help section in Inventor?  You can find it here for 2018 http://help.autodesk.com/view/INVNTOR/2018/ENU/?guid=GUID-564D4AF1-E566-490F-9491-BAAFD208F1BC

I would look at some of these recommendations and see if they help.  If this is not helping let us know.

Thanks,

Hi Arthur,

On top of what Kyle mentioned, I  have some comments. As of 2018, 2019, and 2020, I would say 26K components assembly is mid size. But, it depends on how these 26K components were created. Do you have any of large parts (an ipt in 100MB file size)? Inventor graphics system is most efficient when geometry and graphics objects are distributed among files. When you have parts with a lot of geometry, the performance may not be good.

The graphics driver seems outdated. Please update it. Also, make sure all critical Windows updates are installed.

Many thanks!

Hi @johnsonshiue ,

What do you mean with "Inventor graphics system is most efficient when geometry and graphics objects are distributed among files"

Basically our designs are made of simple I-profiles and plates, with no special/complex geometry.

Windows 10 is up to date.

Graphic driver is installed according latest recommendations.

Any further suggestions?

Hi Arthur,

What I mentioned earlier is about large parts. I have seen cases that the user either derives a complex subassembly to a part or import a complex assembly as a part. Essentially, a part represents geometry of an assembly. Usually, such part takes 100+ MB disc space, which has a lot of detail geometry. If you have a few parts like that, it may drag down the performance of overall assembly. Do you have parts like that?

Many thanks!

Hi @johnsonshiue ,

I have thought that the use of derived parts for large assemblies is the most efficient way to handle and work with large assemblies, looked within Inventor.

The same is the case with the use of "Substitute LOD's" within the assemblies, this is most practical way.

Working with Vault and a Release process there are differences!

Since we have found many issues within Vault Pro (Circular references; missing links; unable to update; unwanted updates; dirty files marked with *; unable tot check in files) with the use of "Substitute LOD's" or Derived parts etc. we don't use this method anymore, with the effect that the assemblies (Large) cannot be handled anymore (Slow performance).

If I take a assembly that has been build with derived parts there isn't this issue regarding slow performance!

So why is there a difference between what you are suggesting in comparison with our findings and understandings?

Thank you for your response,

Hi Arthur,

It is a bit hard to comment further without seeing the actual files. What I am trying to say that, in general, 26K components assembly is not large as of Inventor 2018 and later. If there is a performance issue, Kyle and I need to look into it further. Please share the files with us (kyle.gilham@autodesk.com or johnson.shiue@autodesk.com).

Many thanks!
