frequent freezing on OSX

[d_hg]

I've been regularly experiencing "freezes" of the application on OSX 10.9. This can happen during any number of operations, such as creating joints, stopping a sketch, and extruding a hole.

When the app freezes, the CPU gets pinned to 100% and all UI goes unresponsive. I've waited as long as a few minutes to see if the program would simply wrap up whatever its doing, but it never has. I'll then force-quit the app and restart it. After restarting, trying to perform the action again typically happens very fast so I'm not just performing a computationally expensive action.

This will happen maybe once every 20 minutes of continuous usage, and causes a minimum 3 minute disruption of my workflow.

Is this a known problem, or have other people run into it?

Just curios if @Phil.E 's warnings helped at all. 

To recap:

* Hundreds of bodies in any single component. The design is mostly xref components (about 10) and has hundreds of bodies in both the root and a couple of subcomponents. Open the text commands, ensure you have TXT option checked, and use component.count command. It will show you a list of objects in your design.

* Hundreds of move commands. The bodies are made "out of position" and moved into position with body moves. (this is particularly bad when each body has to compute a different transform against the component origin). If you scroll the timeline, do you see (at times) mostly little black crosses that are body move commands?

* The design itself is 38MB when downloaded. I've tested much larger files that had better performance and no memory/cpu issues. But in this case, size could matter when considering the two points above.

Have you tried?

*Creating more components to distribute the bodies among more componenets?

*Elminating unecessary move commands from the timeline

Some of my questions are:

*Do you have any large sketch, feature, body, or component patterns located in the design?

*Are the threads in any fasteners physically modeled?

I would be interested to see the design. Did you already share it with Phil.E?

Thanks,

Hey Nate,

* Hundreds of bodies in any single component. The design is mostly xref components (about 10) and has hundreds of bodies in both the root and a couple of subcomponents. Open the text commands, ensure you have TXT option checked, and use component.count command. It will show you a list of objects in your design.

==> my design is clean, I only have one or two body per component.

The components.count returns:

With Overrides: LeafOccurrences 43: Bodies 51: VisibleLeafOccurrences 21: VisibleBodies 28: LeafOccurrencesWithVisualMaterialOverrides 4: OccurrencesWithTransformOverides 16

* Hundreds of move commands. The bodies are made "out of position" and moved into position with body moves. (this is particularly bad when each body has to compute a different transform against the component origin). If you scroll the timeline, do you see (at times) mostly little black crosses that are body move commands?

==> I never use the move command.

* The design itself is 38MB when downloaded. I've tested much larger files that had better performance and no memory/cpu issues. But in this case, size could matter when considering the two points above.

==> not sure how to export the whole design in Fusion (apparently saving a distributed design is not supported yet)

For your questions:

*Do you have any large sketch, feature, body, or component patterns located in the design?

==> well, I guess it depends on how you define "large", here's the most complex sketch:

But the general rule is having around 15 sketches per components and they're pretty straightforward.

*Are the threads in any fasteners physically modeled?

Nope.

I would be interested to see the design. Did you already share it with Phil.E?

Yes he has access to the design. I can share it with you if necessary, what's your email address?

Cheers

Unfortunately I haven't found a solution, @Anonymous.

Some observations and notes:

• F360 does not seem to freeze when editing brand new models - e.g. simple ones made from scratch or recently downloaded from McMaster
• I haven't been using the program much since the latest update, so I don't know if that's had an effect.
• More complicated models with long timelines are clearly much slower to work with than simpler models. However there's no indication that this general slowness is related to the freezes.
• I've begun saving after every single edit to prevent loss of data, because as far as I can tell, the crashes are innevitable. Each save takes about 10 seconds during which time the program is locked up.
• It also takes approx 60s for the program to load up after crashing, and another 60s to load the model back into the editor.
• see https://www.nngroup.com/articles/response-times-3-important-limits/ 😞

@d_hg I was looking through the error reports that you've submitted so far and couldn't help but notice that the graphics card on your system has 256 MB of video memory. I note this is below the system requirements for Autodesk Fusion 360. I suspect this is why you are experiencing the performance and stability issues you are experiencing. 

I have a collection of solution articles related to stability and performance in the below link. These may help minimize the problem, but I suspect new hardware is the true solution here.

@Anonymous I was able to get your files from @Phil.E I'm taking a look and seeing if I can reproduce on my end. I'll follow up shortly with my findings, either way.

Thanks,

Okay, good to know. Yeah it's an older macbook but otherwise stable. Thanks
for the info, didn't realize it was below spec.

Im having the same problem on mac, i try to perform an extrude and it stops responding and i have to force quit. it only happens, however, when i try to extrude the area outside of a circle ive drawn. specifically when i extrude negatively to match the edge of the object. no other actions make it happen during my projects so far. ive deleted the project and started from scratch but i keep getting stuck at the same step.

This should really be it's own post. The original post here is several years old, is about a completely different problem.

Can you share the file with me? I can only find 3 crash reports from your entire history and they are all related to the geometry of your design. If you can post the file I can try to diagnose it.

If you are crashing more often or repeatedly, remember to always send in the CER form. This is the only way we know there is a problem.
