Very bad performance

Very bad performance

Hello, i have some problems in using fusion, as it frequently lags and crashes, mostly when rendering and sketching, but sometimes also when simply passing the view on ""complex"" (no more than 10 objects). I find it extremely frustrating as i spent almost a thousand to upgrade my pc, which has outstanding performances on gaming and general cad, except on fusion.
Configuration is:
CPU RYZEN 7 2700X
GPU RADEON 5700 XT
16GB 3000MHZ RAM
Aso fusion is installed on the main ssd and still it's very slow on opening too. I don't know what to do, and i don't accept losing quality with a pc like that, i say this to prevent suggestions like "lower the graphics of fusion", if it goes on like this im gonna charge platform. Thanks

Can you export a design and share so we can see what you're working with? Save as an f3d and attach. Are you working with any imported sketches, SVG or DWG? These can cause problems like you have.

Thanks for the fast reply! Now i cannot share the design as I'm strictly being told not to divulge any information about it, im sorry for that, i know it seemes stupid but you never know. That said, i guess you immedistely pointed out the right issue. This design is the product of many many sketches and extrusions and cuts, in fact, i initally made a first project and i copied a part of it in the new design, as that part was so perfectly and cadually done that it was difficult for me to replicate. So maybe that is the problem!

I have a question then... Is it possible to simplify an object? I mean, now that i have a form i am sure of, can i make like a mold of it and make a brand new object from it? Clear of sketches, extrusion history etc... Thanks!

Something you could try is derive the bodies you want into another design. This will give you just the body without all the overhead of history and sketches in original design also if necessary you could still work on the original and the derived design will update.

 

Having a lot of sketches and extrudes is not really a problem if you keep the sketches simple. You need to be carefull with the autoproject options as they can create a lot of extra load you don't need. Also are you creating assemblies with components? If you're using components are you position with joints? Another performance killer is Capture Position, you should be able to build assemblies without any Capture Positions.

Actually a derived design is what i used... I mean i just imported a part of the old design into the new one, so i guess is it. No there are no components nor joints, as each part is printable singularly.

Hi,

Without any information about your design, even if it is only recreated, the base for halfway useful hints is missing.

Throwing money at hardware does not address modeling technique.

It might be worth some spending some money on advanced training.

Nearly all of the issues of this type that I see are self-inflicted by poor modeling techniques.

 

Run the Tools>Utility>Compute All

Any issues returned?

 

Show a screenshot of only your Timeline.

Any Moves?

Any highlighted issues?

 

Show a screenshot of only your browser (with expanded sketch folder).

 

Show a screenshot of only your Parameters table.

 

I'll wager that I can spot issues without even seeing an image of your actual geometry.

Sure, my skills are not that good, im trying to learn. I spent a lot of money because of gaming, but we all know that usually gaming and modelling need the same platforms. Anyway, i find it stupid to make a program which uses one core only, lagging, ignoring the other 7 cores, resulting in a max of 30% cpu usage... It's like using a toyota engine on a bugatti, why that??

What CAD program is multi-core for design/assembly functions?

 

Still no actionable information.  No screen captures of Timeline or Browser.

(It would really be helpful to see screen capture (in Edit) of your most complex sketch, but I am guessing you can't show that much information.)

Idk im just saying, how is it that the last generation of ryzen 7 performs as well a 4 years old i5 6600? Why can't they make a stabler version for amd? Is it only Intel friendly?

You are looking in all the wrong places. For CAD it's always been clock speed is more important than cores, CAD doesn't work in parallel, you can't start calculating the next feature before the last one's finished. Seen this problem for years, someone buys the latest multi-core processor that has a slower clock speed that the last generation and complaining whatever CAD program they use is running slower.

 

Fusion's only problem is it will let you use poor technique, not always a bad thing if you want to throw something together quickly but not so good for a novice.

 

Really without someone seeing what you are working with it going to be pretty near impossible to help. You might even have found a bug\problem in Fusion and be using perfect technique in your design but no one will know without seeing.

 

You say you're not using components, but it sounds like you have more than one body in the design? If that's so I'd suggest you look at Rule#1 and start using components. This might not be the best workflow for what you're doing but for most assemblies it's the most efficient.
