Not using all CPU power

Torben.pedersen — Tue, 21 Feb 2017 08:41:32 GMT

Hi fellow Inventor users.

I have the problem with inventor, where inventor is "thinking" and getting white screen, and sometimes shutdown.

when I then check the CPU use it´s between 10 and 22 % why do Inventor not use a lot more of the CPU power, and is there anything I can do, so it use more?

Specs

Processor i7

RAM 32

GPU Nvidea K2200

Inventor is a single-threaded application, which means it can only use one core of the CPU at any given time.

There are exceptions, though. FEA and rendering are multithreaded, and can therefore use more than one core.

thanks for the awenser, so there is nothing to do about it ? /:

Depending on your setup, the complexity of your geometry, the complexity of your assemblies, and the amount of constraints in those, there may, or may not be anything to do about it.

It all comes down to what small steps you can take to prevent loading times.

I can't give many recommendations when I haven't seen what's causing the problem.

well okay, it not just 1 part/assembly

the problem is that in all the things I "draw/make" in inventor there are a lot of holes, (over 10.000) and in assembly there are parts in all these holes.

10.000 holes... That's your problem. The geometry is too complex, even if it's just a bunch of holes. Perforation is nigh impossible to handle in Inventor.

Unless it is an absolute necessity to have the perforation on the 3D, I would create an appearance to handle it.

And then I would handle the holes on the 2D files (I suppose it's for CNC cutting and / or stamping?)

yeah thats a lot of holes.

the problem is that our head office WILL have it all in 3D so it´s a pain in the *** most of the time.

it´s not for cutting and / or stamping but same procedure 🙂

May I suggest that you change your workflow so you create everything without holes, and then add the holes in the end?

That way you can work with it, and when it's done and you don't have to change anything else, you can add the holes.

Your machine will thank you for that 😉

If the head office likes to have it, make a small calculation of what is will cost them.
I guess they will give you a very fast PC or they change the way they think. 🙂

I second @Rob67ert suggestion.

Get a timer app and start it every time it loads.

Do that for a week, and tell them: "I spent this much time waiting for my machine.. Because of holes... Are you sure you want for me to be this inefficient?"

Re: Not using all CPU power

Torben.pedersen — Tue, 21 Feb 2017 09:35:44 GMT

the workflow wil be triggy to change, but I will keep it in mind.

yeah I guess I could time my time, thanks for the suggetions 🙂

Do you know which i7 you have?

See if you can find it on this chart.

Re: Not using all CPU power

Torben.pedersen — Tue, 21 Feb 2017 13:37:12 GMT

i7-4790k CPU @ 4.00GHz

why does that help me?

Re: Not using all CPU power

Ray_Feiler — Tue, 21 Feb 2017 13:42:41 GMT

It tells us a faster CPU will not help you. Yours is currently ranked number 3 on that chart and not far enough behind the leaders to make a performance difference if you did upgrade.

I'm with @YannickEnrico,

Try saving the holes until the end, then roll up the end of part to just above the holes while you are working, before saving, etc. Also look into making "Dummy" parts that are just work axis, work planes and work points aligned to your holy part (Or even create a shrinkwrapped or similar part). Then leave that part suppressed or deleted from the assembly until you are ready to submit / vault. Let the Dummy part align the other parts, etc.

Hope this helps,

Kenny

at the moment I´m already supressing the holes, but I´ll keep the other things in mind thanks 🙂

Hi @YannickEnrico

I just have question regarding type of core used by Inventor Application.

Diving into details as there are much advanced processors available in market, something that is applicable or not when it comes to processors and running of Inventor, that which type of core in processor is Inventor designed to use?

Performance-core

Efficient-core

Low Power Efficient-core
