I received a production plant from a CAD system. as a step file. Lots of parts. File size is 64MB. Not a lot.
I imported NURBS and set the quality to 0.3.
9.5 Billion triangles!!!
I have 64GB RAM and 48 threads (2x Intel Xeon CPU E5-2692 v2 @2,2 Ghz). Not the newest.
I can’t handle the scene anymore. Should I import it with a NURBS quality of something like 0.05 or so?
Whatelse can I do while importing?
In Germany we know a phrase “stack low”, meaning start with a low value.
I would start to import such a huge CAD assembly with a value of 0.01 and analyse the results.
Based on the look, I would re-import the assembly with a higher value (note: between 0.01 an 0.1 is a factor of 10, but that doesn’t mean you get ten times more polygons).
If the overall look is good, then I would re-tesselate some cylindrical parts to get smoother results.
To check the import quality, I use the geometry view and sometimes the option to use MatCaps.
Or hire a professional consultant, that help you with this start. So you get best practises that helps to run the next project easy and smooth.
Hope that helps

Thanks for your reply Marco.
Since I was always pretty spoiled with RAM and cores I’m not so experienced with too big scenes. I’ll reimport the scene and try it again.
Meanwhile I bought a new computer for this (I know, pretty extreme) and had my current work station being checked. Seems that there is a problem with the RAM that could cause the problem. So I’ll have a backup work station or use it for network rendering.
But the advice to import in between 0.01 and 0.1 is helpful. I’ll give it a try.
Greetings from a happy INNEO customer, Markus
Happy to hear that you as a customer is happy 
I imported the whole scene in 0.01 quality but every part is now in 0.1 tessellated.
I’m running V 2024. I can lower single parts to 0.01 but the machine can’t handle the process. Once it crashed and it stops mostly.
And this is with my new computer with 80 cores and 384 Gb Ram.
If I manually lower one part and make a pattern it’s lighter. But I think there are problems with the model. I heard now that it was imported and exported through different CAD systems and they already fixed it.
