Fusion 360 hardware for modelling performance

[mateusz.goralczyk]

Does Fusion 360 depend on single core of CPU while modeling or multiple core? What hardware components impact modeling performance in Fusion the most?

Single core processor performance is key!

The math and algorithms used in the geometric modeling kernels of CAD software (not just Fusion 360) don't lend themselves to multi core processing in most cases.

I have currently i7-7700K with 4,5 GHz single core in my PC and 36gb ram.
With more complicated models Fusion have hard time. Is there a point in
looking for new CPU if single core matters most? If so then with on that
will not be too expensive?

Hi,

1. with 4.5 GHZ you are already at the higher limit.
2. in most cases, the long calculation times are caused by complex and insufficiently defined sketches and large patterns in sketch mode.

I do my sketches very carefully and take attention to make them as simple
as possible and to use as little projections as possible. I do lot of
complex surface modeling that needs to be rebuildable with parameters.

I my not so insignificant experience, most performance problems stem from less than optimal modeling workflows.

What I mean with "not so insignificant" is that I have been using CAD for over 30 years and have used Fusion 360 since 2014. I have analyzed thousands of designs here on the Forum.

If you can share one of those designs I'll take a look at it.

If the modeling workflow ends up not being the problem, I'll tag someone from the Fusion 360 development team.
