Extreme Slow response in Heavy Assemblies

[patrickautosm]

1. I am working on a Assembly with more than 4000 components with no Errors and Warnings , Only solid Modeling parts. Now as the Number of Components are Increasing , response is getting extremely slow. If i i wa to update any linked part i i have to wait for a minute to let it Compute. While moving sub assemblies there is a very huge Lag. Opening such files takes more than 3 minutes. Creating Drawings with heavy assemblies is also very difficult because of the slow response  marking each dimension take multiple seconds in snapping points.
2. I am running a PC with 12 Gigs Ram , 8 Gigs GPU , i7 processor 3.4 ghz ,high Speed Internet Connection.
3. I have both types of assembly  one with Joints and another with Rigid Grouped Subassemblies. Both have same behaviour except one that assembly without joints takes less time in Updating Referenced Components as it doesn't have to compute each joint.

4000 components is a LOT. I'm not surprised about the lag as that's a huge computational load.

You could try to optimise the assembly somewhat using things like patterns instead of duplicate components where possible.

This article covers these kinds of optimisations: https://knowledge.autodesk.com/support/autodesk-hsm/troubleshooting/caas/sfdcarticles/sfdcarticles/P...

Hope this helps!

Does that include PCB assemblies?

Or, do you use a lot of fasteners from, say McMaster Carr with modeled threads?

There are a number of  things that can affect performance and without more details, it is hard to determine what exactly is the problem.

4000 components is a lot for Fusion 360!

I have given a lot of hours in resolving this by reading all the Forums related to it . I have used Patterns everywhere possible and for Fasteners i have made it a part separately and then referenced it assemblies. I have both type of assemblies with one with referenced fasteners and other without. I have one with joints and one without joints. The file without joints doesn't take much time in Computing whenever i update any referenced component but making a drawings out of both of them is a huge trouble.

No there are no threaded Fasteners in the assembly , i have tried all the possible ways to reduce the load from file given in the Forums.

I think since you have so many parts in the assembly this is just the limitations of the software. As has been said, 4000 really is a lot of components and you’d see a slow down with any CAD program when it gets that high.

One last thing you could try is looking at any background processes on your PC and turning down the main graphics settings and window effects. I’m not super hopeful that you’ll get a noticeable boost from that though.

I somewhere Agree with your Point that it might be the End of Fusion Capabilities but if we see at Fusion's tag line it says Make Anything. Also for a Industrial Designing 4000 components is not much. I have worked on assemblies with 10000 Components on the same PC in Seimens solidedge. One of my colleagues is also working on a assembly with 35000 Components on Solidworks. They seem to be working smoothly.
