Inventor Performance

mk92 — Thu, 03 Dec 2015 13:55:44 GMT

Hello,

i have an generell question about loading assemblies with more than 1000 parts. I have seen that my computer uses only 13% of my CPU (Xenon 3,5ghz, 8 cores) power and my RAM (DDR4 1866Mhz) has 75% space left and use a SSD.

But when i load a big assembly my ram loads only like 2-4MB per second.

Which are the main components to speed up my load speed? The performance while i have the assembly open is nearly perfect!

Regards

Assuming your system meets the required standards for using inventor.

There are a couple things you might want to look into to help you with large assemblies.

First, look at shrink wrapping your assembly.

Next, levels of detail

And lastly, iassemblies.

Depending on your application, one of these should help you with your large assembly.

If this solved your issue please mark this posting "Accept as Solution".

Or if you like something that was said and it was helpful, Kudos are appreciated. Thanks!!!!

To my eperience what helps most:

Fast CPU (not even a lot of cores, because most of the times Inventor use only one 🙂 ) -> But bigger ghz.

At least 16GB RAM, even more is better (for importing step files for example aroung 1GB - 16GB RAM will be out in a second).

And SSD is of course really good. Have in mind that today exists even super fast ssd (see my attachments to see diference between SSD and superfast ssd)

But of course even super expensive HW will be lost if you don't work properly with large assemblies as @Cadmanto already wrote.

Yes hardware plays an import role in Inventor performance but other items do as well.

Some other things to consider outside of hardware specs

Not working across a network
Incorrect application and/or project settings
My model can’t find my files (resolve link)
Non-unique project file name message appears a lot
Incorrect workflow being used
Content center parts are missing
Duplicate files – not sure which one to use
Large assemblies - http://beinginventive.typepad.com/files/inventor-deep-dive---large-assembly-instructions.pdf
Numerous constraints
Windows Updates
Anti-Virus/Firewall settings
Clean out your temp folder located under your username (Windows) profile

With more than 1000 parts I am sure you are using Express Mode, that gives you some of the best results when opening the assembly. You can even choose it when you opening it by choosing options first.

Inventor will open the assembly with cached graphics and on demand load more components as it works with constraints and other tools. Opening the assembly full means it has to load all the files one at a time at about a rate of .2 microseconds per file.

Also if you turn off add-ins you don't need that can help you get in there faster as well.

Tools --> Addins

Thank you all. I will try to sum up what is usefull to me.

1. I have to load the full assemblie, not in express mode, because i have to work in this assemblie.

2. I also work with bigger layouts in the Factory Design Suite

- Hardware:

3. CPU - More Power per Core

4. RAM 32 GB - Dual- Trippel Channel really important?

5. SSD - RAID 0 ?

Hi mk92,

If all else fails, go thru your parts especially the once you imported from a step and have a look at errors on features and or sketches, contrains in assemblies (try reduce with insert mate ex, or go for a top down assembly style), size of design files (are any unusually large?).

2 SSD drives in raid 0 are greate and when loading designs and drawing this is a big help. If you are running a dell system, try their optimizer to squeeze all the power from the pc and the report tool to find the bottle necks.

If you built the workstation by your self and feel the memory is the bottle neck, double check they are correct mounted in the correct slots, check your motherboard for wich once are working together 1/3 2/4 very comming for 4 slot.

Happy bug hunting.

1. Express mode is fully automatic, and you SHOULD use it all the time. When you start diggin' down the parts and assemblies Inventor will automaticly fully load these assemblies and parts. So turn it on, enjoy the performance and work as normal.

Re: Inventor Performance

mk92 — Fri, 04 Dec 2015 10:03:34 GMT

So lets sum up again:

CPU

- ~8 Core with high Mhz to gain speed with single Core Tasks

RAM

- ~32 GB high Mhz split to as much slots as possible to gain bandwith (maybe 8x4GB)

Hard Drive

- 2 SSD, Raid 0

- 64 Bit

Any other tips? 😃

About HW that's it (maybe that superfast ssd insted of ssd) - but this is already a nice overkill for Inventor assemblies.

So maybe really look and understands the work best practices with large assemblies. Otherwise all HW is kinda lost 🙂

CADMonkey4Life — Fri, 04 Dec 2015 11:05:23 GMT

Sounds like a beast to me 😉
1000 parts isn't super duper large and you shouldn't have any problems with handling that size of a model. In the help wiki in Inventor, search for Large assembly mode. There's a whole chapter about handling large assemblies with Everything from turning of shaded with edges in view to change your filter from Component to part (shift + right click). I can go on and on about handling large assemblies with my customers and rarely it's down to the hardware. 🙂

You've gotten some good tips and trix here so let us know how it goes 🙂

Hi,

the single core catch would be interesting to see on a

9550 AMD with 5GHZ turbo speed.

Non certified for 24/7 though- which is kind of a set-

back in a professional environment.

As of architecture. An 3550 XEON does not perform as

well as a 2670v2 XEON does. The turbo should be the

same. As of base clock, the newer one is 500 Mhz slower.

The single core turbo ratio can be changed on some ga-

ming mainboards. Is very interesting.

Some day next week I might be able to supply some HP17Z

mobile Workstation PCIE SSD figures and see to HP´s claims.

Hopefully it´s not a integer divider scenario or something in

the way the performance plus in CAD shows. They said 30 to

50%

I would want to see some DDR2 to DDR3/4 figures...

Kind regards

Daniel

Single core in all its glory 90% of the time. But don't forget drawing views that uses more than one core. 🙂
Dual CPU with double memory banks are a good way to go aswell 🙂

Sample configuration:

INTEL Xeon E5-1630 V3 3700MHz 10M Cache 4Core
32GB (ECC Registered DDR4 2133
AMD FirePro W7100

The SSD´s are quite right... The Xeon delivers the highest

single thread performance at this point, not advertising.

The AMD Fire is superb for Showcase and Inventor and

as it´s predecessor runs very well for the price tag.

Tom´s Hardware did some Benchmarks some time ago.

The ram... have not heard the colleague I built it for com-

plaining. Yet clockspeed and ram still spells unstable for me.

With supermicro boards we have not had a single freeze or

crash reported in moths, the render workstation ran for 30

days straight before I did shut it down.

Kind regards

Daniel

@CADMonkey4Life Or simplifying of assembly (Shrinkwrap) - I use that a lot and that use all cores up to 100%.

Or RRT (Raytracing) - rendering in Inventor.

Re: Inventor Performance

Logos_Atum — Fri, 04 Dec 2015 13:01:41 GMT

More channels surely do!

Re: Inventor Performance

mk92 — Fri, 04 Dec 2015 13:06:51 GMT

Thank you all for your help 😃

I am still planning. So the results need some time!

I tried to work with Shrink wraping, also in the Factory Design Suite. Works quiet good, but the filesize is really big and layouts with arround 100 assets need a lot of time to shrink wrap...

The Dell Workstations give a good selection of Intel Xeon CPUs but i need time to check which one is the best for me!

Kind of offtopic but, is there a way to Save from Inventor to Navisworks directly?
