Am I doing something wrong? Inventor is too slow.

Anonymous — Sat, 10 Jun 2017 06:08:09 GMT

I simply do not understand, should I switch operating systems to 7 or 10? I have Windows 8.1 currently. My workstation is an Intel i7 6900k overclocked to 4.2 GHz with 64GB of 3000 MHz RAM, I am not thermal throttling at all. My OS and Inventor HSM Ultimate 2018 is installed on a Samsung 960 Pro M.2 NVMe SSD and I have an overclocked Nvidia Titan X...why is my CPU load between 6% and 16% with 2-4 cores out of 8 peaked and the others are nearly untouched in comparison, less than 20% RAM used and my GPU load is 0%? My assembly is saved to my boot drive and every bit of function I attempt to do takes an hour if it does it at all.

Why is this CPU based?? I understand I have close to 2,000 parts in this assembly that I am attempting to load, I do not expect it to be instantaneous...however I would like to work on it tonight and the fact that the hardware I have isn't being used to its potential is frustrating to say the least.

Is it me? I understand things have to be done in order, so I'm waiting for nearly 2,000 components to do what they need to in order accurately. Why is this not putting my components under a heavier load??

Inventor is CPU clock speed driven. For modeling, Inventor can only use a single core of your CPU. It can't model downstream features of a part until the first features above them are modeled. This means that Inventor must work down your Feature Tree to build your part. The FEA and Drawing view placement are the only areas that truly make use of other cores.

I have included a good link for Inventor and Inventor performance. There also is a Bench Test that can be downloaded to analyze your system performance.

Hi Kevin,

Many thanks for sending us the feedback! Indeed, Inventor is not fully multi-core or multi-threaded application. However, certain processes in Inventor do have multi-core or multi-threaded ability. Please take a look at the link below for more information.

In addition to the list, Inventor FEA solve is also multi-threaded. If you are aware of a 3D feature based parametric solid modeling CAD system supporting full multi-core or multi-threaded, please let me know.

Thanks again!
