How many crashes per hour is considered normal?

[sebastienSQA5P]

Hi everyone, I'm running the latest version of Fusion 360 on a 3.3Ghz Macbook Pro i7 with 16GB of Ram running Mojave 10.14.6.  Fusion crashes around 4-5 times an hour.  I'm curious as to what is the "acceptable" number of crashes per hour for this premium product?

Does crash reporter come up after each crash?

[sebastienSQA5P]

Yep.

[sebastienSQA5P]

I'm paying attention now, the "post to Autodesk" dialog box and subsequent browser window opening only happens about 30% of the time.

I use Fusion 360 every day in my day job and often after work for personal projects and to help other users on this forum. I cannot recall the last time when I was able to reproduce a crash.

Can you share your model and in general more data ?

I don't think I have crashed that many times in the past 4-5 months.  Maybe that many, but running pretty stable this year.  Sketches... ...well that is another story.  Not crashing, but not entirely predictable yet either...

As @TrippyLighting suggested, Attach or public link to a project that exhibits this behavior.  Fastest way to get something fixed is with real evidence that exhibits the behavior.

Fusion should run for hours without crashing. Unless there is a specific problem that needs to be fixed.

Unfortunately I can only find 4 CER reports from you. Those I found characterize a problem with data, i.e. a specific design.

• The reports are all in the last few days. 
• Two involve PCB workflows
• Two are unique for you (nobody else has crashed the same way yet).

Can you share a design link and some steps I can take to repeat the crash? This would be a good report to log.

Thanks for your comment.  Ok, I'm diligently clicking "send report" so you should see about 10 more errors from me now, all in the last couple of hours.  I was sending the reports to Apple which obviously doesn't help you.  Although I can't share the project publicly, and this is different to what I was doing before, I can reproduce a fatal error very simply now:

Open Autodesk
» Create a new project folder "Project name"

» Create a subfolder "Pallet racks"

» Download this file from Grabcad (I'm not the author): https://grabcad.com/library/pallet-rack--5

and upload the contents of the .rar file into Pallet Racks folder, selecting "pallet racks.SLDASM" as the primary.  (Note it will throw an error as there's a missing component in the file, but that doesn't stop the upload)

» Create a new project and save.
» Create a new empty component, name it "racks"
» Import the Pallet Racks file uploaded above into the empty component ("insert into current design")
» Edit the aforementioned file, delete the "horizontal bars" and use the "create rectangular pattern" feature to "add more shelves" (I don't think the exact numbers / dimensions are important)

» Use the "create rectangular pattern" feature and try and select the imported component.  Fusion will freeze with the coloured pinwheel spinning, causing it to hang and crash.  I can move the window around my monitor, but interestingly the UI elements stay fixed on the screen.  Only way to get out of it is to do a "forced quit."

I'm hoping you can replicate.

The previous crashes were a little more involved, and it appeared to be when I had my PCB library open up at the same time as the schematic and PCB. (It's not a very complicated board though, only around 40 components) 

[sebastienSQA5P]

Further errors, I took a screenshot as there's no autodesk reporting error on this.  Has to do when I have my component library open at the same time as a (new) PCB design / schematic.  I'm trying to update 3D files for the components which causes inconsistency errors between the schematic and PCB.  Both are open at the same time.  I've had this a few times on different project designs.

Hi,

In the design with the pallet racks, I take it you are force quitting each time. That's what the reports show.

Fusion is in fact not crashing. It is busy doing a compute on a very complicated piece of geometry. That design looks like models used for the manufacture of pallet racking. As such it is very detailed with edges and faces you'd expect to find in a CAD model for manufacture of these metal parts. Are you going to be manufacturing racking? Or do you just need to use it do to a layout design for your warehouse? 

For instance: If you examine the pallet rack design, it has the following characteristics:

The upright columns alone (4 of them combined) contain:

• 28,656 edges
• 10,360 faces

The other parts, in total have a few thousand more faces and edges.

When Fusion is working to select, move, pattern, etc. this geometry is computed by the modeling kernel. This will necessarily take a long time, which is what you are finding. The force quit crashes show that Fusion is busy trying to keep track of all that geometry as it prepares to pattern it (or move, or selecting it, etc.)

If you don't need to show or use all that complexity, my suggestion is to replace the complicated parts with simplified versions, see attached. Be sure to delete the complex components after you replace them.

Please let me know if you have more questions.

[sebastienSQA5P]

Thank you - I'll do that (I certainly don't need that level of complexity)

I do think it's unrelated to the other issue, which I believe is down to having a library imported from Eagle and trying to fix the 3D files attached.

I suspect the root of your "crashing" problem is with the Electronics side of Fusion 360.  If you have a look at that forum you will see lots of complaints of how buggy it is.  

In regard to @Phil.E 's comment on the seemingly endless pinwheel effect, it may indeed just be a long processing time, but often when Fusion 360 Electronics is involved I have left it run overnight and it's still spinning the next morning.  Sometimes it really is just taking a while to do the computations, so my rule of thumb is to let it have 5-15 minutes (depending on my mood at the time), then force quit if it hasn't finished by then.

[Phil.E]

@fheineman  I appreciate your analysis and input.

These are separate issues. The overly complex racking model is using modeling code is stable code, it just takes a while to handle such a massive request. 

The electronics related crashes that @sebastienSQA5P  was experiencing ended some time ago and have not appeared in the latest release. 

I'm sorry to hear you've had some trouble with the electronics workflows, I would say these are passing issues. Have you continued to experience these problems in the latest release? If so, please post about it in the electronics forum, there are engineers watching those reports and are happy to help, or hear about your issues.

And as always, send in every CER report you see. This is how we know where/when to focus on crashes.

Thanks!

Hey Sebastian,

           I am getting the same problems.  With the new update, fusion keeps on crashing!  Is yours still crashing??

[g-andresen]

Hi,

Please describe the observed behavior more concretely, preferably in a screencast.
