Computer Power

eddgto — Mon, 21 Oct 2013 17:39:52 GMT

Using a 2013 Mac Pro 12 Core, 28 GB 1333 MHz Ram, Geforce GTX670 VRAM 2048 MB. Should this be an advantage for modeling in Fusion 360? Seems to me Fusion 360 grinds it to its knees. It barely moves.

The computer looks good, so I have to assume that it might be data set specific.

Can you describe what you are working on?

I'm trying to modeling a 1956 Plymouth car as accurately as I can. About 2/3s done.I have a number body versions in this project.

Cool Project!

Do you know if the there are many star points in the model? You may consider trying the Enable Better Performance feature from the Sculpt ribbon > Modify drop down menu.

You may learn more about this feature in the below video.

Please keep us updated on your progress.

Hi,

Might it also be possible to provide some details the types of performance problems you are seeing? In particular:

Is moving/rotating the model in the graphics window slow?
Are any particular modelling operations slow?
Are you experiencing unexpected hanging/pauses?
Does the Activity Monitor (Applications > Utilities > Activity Monitor) show that you have some free System Memory available?

This will help a lot in tracking down what the bottleneck might be.

Many thanks for reporting this!

Jake

Using better performance mode.
Slows down in Sculpting after about 10 minutes of use.
Scroll up to get in close to select hard to get edges it starts slowly jerking.
Can't Pan or Rotate with mouse.
Will scroll up and down and rotate fine when hit house icon and reduces to normal size.
Scroll back up to get in tight to edit fine detail starts jerking very slowly.
Still jerks slowly even after I close car body and want to edit the the small Chrome tail fin body.
I am in adaptive snap fixed .001.
When I try to turn adaptive snap off it's constantly turning back on on me.
Fusion 360 CPU usage under normal operations runs between 1.25% and 12%.
When I scroll up large to edit fine areas it hangs, slows, jerks Fusion 360 CPU usage jumps as high as 120%.
Fusion 360 is using 1.2 GB of memory leaving about 22GB of memory free.

So this is disturbing, we agree.

cold you direct message me a screen shot of the model? I just don't have a feel for how complex the topology is. We know there is a slow down with very large tsplines bodies and I'd like to see how big yours is to see if it might fall into that case. Either way its not right but want to try and eliminate possible causes.

Also some other quick things to try.

Can you turn off all the effects lie anti-aliasing, shadows and such?

In the preferences can you look at graphics and turn selections to simplified.

Do any of these changes help?

Also, regarding a few of the things you mentioned:

Are you using the Perspective (or Perspective with Ortho Faces) camera? If so, it might be worth switching to the Orthographic camera when working on details up close. It would be interesting to know if this resolves any of the jerkiness you are seeing.
Mouse shortcuts for view panning and rotation are available on PC mice with a middle mouse button/scroll wheel. Click and drag MMB/scroll wheel button will pan the view, and Shift-drag MMB/scroll wheel button will rotate. If you're using an Apple Magic Mouse or Magic Trackpad, you can also perform multitouch gestures on the mouse/trackpad surface to manipulate the view.
The Adaptive Snap setting should persist once set; are you finding that it resets immediately, or after performing some specific operations?

Really appreciate the additional details, we'll try to get to the bottom of these issues.

Many thanks indeed,

Jake

I've been testing your suggestions this morning and haven't had any issues. Working great! Thanks for your help. Edd

I don't see it?

These are suggestions Jake Fowler has given me to help me solve the problems I was having and they did. Thanks for your help. Edd

Hi Edd,

That's great, glad to hear that helped!

We'll still take a look into this issue, to see if there's anything to improve the interactivity at close zooms: we'd obviously prefer to avoid any jerky behaviour if we can.

Please do let us know if you continue to encounter any problems.

Many thanks!
Jake
