Very low performance on high-end PCs

Anonymous

I have problems with my computer when using Fusion360. The program gets stuck when I try any movement, even if it's very simple. I leave you the specifications of my computer and a video where I show the problem.

 

https://www.youtube.com/watch?v=gP_7iTdNY6k


Ryzen 3900x CPU (12 cores)
Ram 32GB ocz 3200mhz
HD: Samsung 970Evo 256GB (40GB free space)

[GPU Information]
GPU Device: NVIDIA GeForce RTX 2080 Ti
GPU RAM: 11136 MB
GPU Driver API: DirectX 11.0
GPU Driver Version: 451.48
GPU Driver Date: 06/22/2020

[Graphics Effects Settings]
Anti Aliasing: Off
Ambient Occlusion: Off
Object Shadow: Off
Ground Shadow: Off
Ground Reflection: Off
Selection Display Style: Simple
Transparency Effect: Better Performance

[Limit effects to optimize performance]
On


I've tried the following things:

Uninstall the graphics driver with "Display Driver Uninstaller".
Update Bios and Chipset .
Uninstall Fusion with Fusion 360 Cleaner .

Can you export your design as an f3d and share here?

I am doing a 3d design course in which I follow step by step everything described by the teacher. It has happened to me with each and every one of the nine models in the course.

Thanks for the help.

Did the teacher not describe how important it is to fully define your sketches?

 

Is there a logical reason that you did not place Sketch4 at the Origin, or did you simply miss and then not define the sketch?

 

Is your Sketch8 on the correct plane?  (I will make significant wager that it is not, as the subsequent Split results in an asymmetrical geometry.)  Are you sure that it shouldn't be on the YZ plane?  Hard for me to follow since your sketches are not fully defined.

Can you provide some more information about this 3D design course?

Is this an in-person course or is it online?

Is it free or paid?

Is it through a school or other institution? 

etc.

Sketch 4 was used to make a surface that was then rotated 26º. I can't answer you much more since the course is basic level and I'm just starting.

It's face-to-face and I get it from a friend for free.

You don't have to explain to me what was done - I can read the history.

You are missing Horizontal or Vertical Constraints.

You missed the Origin when placing the polygon for Sketch4.

And your Sketch8 is on the wrong plane. (If only I could spell horizontal?)

As you say, the design is asymmetrical. It was designed that way.

That would cause the low performance of the pc?.

Would you like to make a wager?

Can you provide your source information?

Your model does not look aesthetically pleasing.

Isn't it obvious from my image comparison???

Yes, if you are trying to get Fusion to do something that is not logical.

If you want real help - I strongly recommend that you Attach each and every one of those nine models.  Someone here will give professional guidance that will set you on the right path to modeling success.

Given the content of your designs and the ongoing discussion, you might want to invite your friend to participate. It would seem to me that your friend will need training on the basics himself.

 

Any and all of the issues @TheCADWhisperer has identified would be amongst the first things that should be taught to a beginner. I understand it is fun to go ahead and create 3D geometry quickly, but if the design is not based on a solid foundation e.g. properly constrained and dimensioned sketches, then that cardhouse can crumble rather rapidly.

And to answer your earlier question this can easily lead to Fusion 360 "hanging" for a while. Fusion 360 will try its best to re-create the 3D geometry-based on he new/changes input, for example when you drag that sketch line. However, this can easily lead to a situation where creating geometry is difficult and requires a lot of computation.

Properly constraining sketches at least to the degree that everything except those elements you might still want to adjust is constrained can make that a whole lot faster and more enjoyable.

Thank you all for your help but I don't think such a simple design is the cause of the performance problems. The program is simply hung up with the save action. It may be caused by some software on my computer that is interfering with Fusion.

As soon as I can, I'll find a better teacher or sign up for design classes. Thank you.

1. If you ask Fusion to do something illogical (as shown in your video), then I would expect to see issues.

2. The issue you showed in your video has nothing to do with "save action".  

 

I recommend that you Attach any *.f3d files that you experience any issues with.

These issues can be diagnosed and resolved.

If you still have some issues, try setting your preference for your graphics from "Auto" to "Direct X9". . I had a similar issue with some odd slowdowns with a similar Ryzen/Nvidia issue. I was having a slowdown when moving large mesh objects that I hadn't encountered before.

I do all sorts of illogical things with Fusion and its just fine. If Fusion will do it, its logical. 🤣 Its about the final result and getting your ideas down. 😘

I was able to reproduce the behavior ...

 

The better way to do exactly the same thing is to use "MOVE FACE". It did the same thing but then doesn't require all the recalculation that moving the edge line with "CHAMFER" will. Afterwards there are a few artifacts to clean up from it but its much much faster. And it locking up reminds me of the issues we once had with Filet... Filet and Chamfer should be used only when the adjacent geometry is relatively simple. It takes alot of processing power to recalculate if you have weird surfaces adjacent to it.

Video to follow. Nothing you did was wrong it just certainly wasn't the most efficient method. 

The great thing about Fusion is it has no hard and fast rules.. The BAD thing about it is, it probably SHOULD. 🙂 When a chamfer takes up more than 3/4 of the total surface of an edge, it should say "this is about to really cause some slowdowns: please choose another method". Some other softwares do this and Fusion just seems to be starting this now.
