AutoCAD 3D - Performance issues

AutoCAD 3D - Performance issues

Anonymous
No aplicable

Hi,

 

We use AutoCAD for 3D assembly of our systems (Scaffolding). I have two computers that I'm using for this. One laptop and one desktop. The thing is that the desktop computer is almost as poor in performance as the laptop, eventhough it has much better spec. 

 

My laptop has the following spec:

 

Windows 10 Pro

Lenovo ThinkPad p51

Intel i7 7700HQ 2,8GHz

16GB RAM

NVIDIA Quadro M1200

SSD HD

 

The desktop has even higher spec, dont have acess to it right now.

 

I have learned that Autocad does not utilize all cpu cores for 3D modelling. So should I look for a computer with higher CPU speed and less cores?

 

Can anyone help me increase performance? What is the best computer for 3D modelling in AutoCAD. And which hardware is crucial? 

 

(I know that AutoCAD is not the best software to perform these tasks, but we are an international company with 2000+ employees, where AutoCAD has been choosen...)

Your file's content, complexity and file sizes (and where you store files and how you link to them) also affect performance as much as PC specs do, so do your workflows: so provide a lot more information/details, processor speed alone is no silver bullet, and you just cannot spend enough money to see significant mind-blowing improvements.

Hi!

 

Thanks for the reply.

 

In the modelling space I use both vector graphics, and solid objects. I have tried using different "view" options, and have found that the wireframe option has the best performance for vector graphics, and for solid elements, i use the realistic view.

 

In the layout space i also have performance issues. Especially when trying to make section views etc of solid objects. 

 

Small files also generate performance issues... Off course file size, and content effects the performance. But what is the best settings for working in 3D? Is there any guide lines out there?

 

What kind of details do you need to suggest settings?

 

Thanks.

Show your work: post typical project DWG files (minus any sensitive client information), lets see if folks in these forums can see what options you can employ, if any.

 

Also...

Which exact AutoCAD variant and year version do you all typically use?

What year version do you save your files to by default?

Level of detail is very important when working with 3D solids.  I once had to work with a model of a distillation tower which just craaaaawwwwled no matter the hardware.  Turned out someone had modeled every detail of every tray (several dozen in a 100+ foot high vessel).  There was a similar problem on another project where someone had modeled several kilometers worth of chain link fence in detail.   Only add details which do something for you, avoid adding those which only add "pretty".

 

Also look into using Navisworks for viewing models shaded and in context.  It's built for real-time navigation and display of very large models, and can easily run alongside AutoCAD.
