Corrupted Files

[mpulliam6CT22]

Hi,

I updated Fusion 360 to 2.0.286 after not using the program for a few months.  I've tried to open 4 projects but they are all listed as corrupt.  I've restarted Fusion 360 but the result is the same - corrupt.  These projects worked fine a few months ago.

What is going on?

Error Message:

Could not open file: 535108 assembly v1, Version Number: 1, Error message: Ok

Attached are the Diagnostic Logs

Thank you!

Hi @mpulliam6CT22,

Thanks for posting! I am sorry to hear about these problems that you are having trying to access your designs. As of right now, I'm not too certain what happened here, but I have downloaded your diagnostic logs (thanks for sending those by the way!) and have begun investigating them to see what I can find.

I will circle back here once I have something to share!

Cheers,

Hi @mpulliam6CT22,

So sorry for the delay in getting back to you!

It definitely looks like the file has become corrupted. Unfortunately, the log files didn't tell me much about what specifically caused the corruption. However, I have enlisted the help of some member of the development team who would like to have a look at your design to see if they can figure out what happened here.

Would you be able to share the design with me? To do this, you are going to want to navigate to myhub.autodesk360.com and sign into your account. Once you get signed in, navigate through your projects to the design that is displaying this error (535108 assembly v1, if I'm not mistaken) and export a Fusion 360 Archive file of the design by clicking the downward pointing arrow and selecting "Fusion 360 Archive" as shown in the image below.

Thanks in advance! Please let me know if you have any questions or concerns. I look forward to hearing back from you!

Cheers,

Thanks!

I think the problem involves any STEP File that I downloaded from Servocity and uploaded to Fusion 360.  I used a lot of their parts in my builds.  I have their entire inventory and it was working not too long ago.  Any design I have that includes any of this inventory seems to be corrupted now.

Thank you for taking a look,

matt

Hi @mpulliam6CT22,

Thanks for sending that along and so sorry for the delay in response!

I was curious, so I uploaded the design and tried to open it on my machine (before using any of my ninja text commands to see what was going on) and was shocked to find that it opened with no issue. See the screenshot below.

I'm not too certain what happened that caused the design to open, but I think we can get you back up and running! 

First could you navigate to the following directory?

C:\Users\***\AppData\Local\Autodesk\Autodesk Fusion 360\*UniqueID*\W.login\F

Couple things to note here - "***" will be the username that you log into your machine with, and *UniqueID* will be an alphanumeric ID associated with your Autodesk account. For instance, mine is WAPSJRUV92MF (also, I can see your ID because that folder gets packaged up in your diagnostic log files - I'll send you a PM with that in there).

Once you get to that directory, you are going to want to search through that folder for "_535108" and delete the ._xx file and the .f3d file in there. Once those have been deleted, restart Fusion 360 and try to re-upload the design 535108 and see if that allows you to open it up in Fusion 360?

I hope this helps! Be on the lookout for a PM from me and please let me know if you have any questions or concerns!

Where would I find this directory on a Mac?

[mpulliam6CT22]

Found it in the User Library/Application Support/Autodesk/Autodesk Fusion 360 folder

[mpulliam6CT22]

So basically your saying I need to delete all the local .xx and .f3d associated with any corrupt file, then re-upload the original .step file - basically starting over.

I spent hours originally uploading all these files (hundreds) and organizing them.

Even if this does work, how do I know they won't get corrupted again next week?

[mike.tessier]

Hey Matt,

That was my mistake - I had misspoken in my last post, you actually should not have to re-upload the designs.

The reason I am having you delete the ._xx file and .f3d for 535108 is because I think there is something about these files in your local cache that somehow became corrupted. I believe this is the case because I was able to take that .f3d file you pulled from A360, upload it through my data panel and open it just fine on my machine. By having you delete the ._xx and f3d files, we are telling Fusion 360 that it needs to re-download that design from the cloud and thus create new local cache files for that design. But this is just a theory I have right now.

Should you be able to open the design after clearing the local cache, then the next task becomes figuring out where exactly the corruption is happening. I apologize if it seemed like I was going to have you redo all the work you had done previously in getting those STEP files uploaded! I hope this clarifies things!

Cheers,

There were "_535108" files in two different folders, I deleted said files and emptied the trash.
Fusion 360 was running and I tried to open the "_535108" file w/ same corrupt message.

I re-trashed the "_535108" files and restarted Fusion 360.
I tried to open the "_535108" file an got the same corrupt message.

Didn't work for me.

Hi @mpulliam6CT22,

Thanks for getting back to me and sorry for the delay in response! I have been talking to a bunch of different people internally trying to see what we can do to get this issue resolved for you.

Unfortunately, I am really uncertain as to what is causing this, and for that reason I would like to log a bug for the development team to review. However, they just need a little more information. Would you be able to send me your system profile file in a private message? This will allow the development team to try to re-create your machine environment to see if there is something about your setup that may be causing this issue (we aren't certain that it is something on your system - this is just a test). Luckily, we have a great article, linked here, that describes how to go about collecting this file.

Thanks in advance for the information! Please let me know if you have any questions or concerns. I look forward to hearing back from you!

Cheers,

[mike.tessier]

Hi @mpulliam6CT22,

Thanks for sending along that system profile file! I just finished logging up that bug for the development team to review. It has been logged as FUS-31383  for your reference.

I am sorry that I do not have better news at this time, however, as soon as I receive an update from the development team I will circle back here to share! Once again, I'm so sorry that you are experiencing this issue and thank you for your patience while we continue to work through this.

Cheers,

@mike.tessier

I've re-uploaded all the .step files that seemed to be causing problems.  I checked a random file and it seemed to load fine.  Then when I created a new project and tried to use a .step file that I actually needed - I got the same error message!  Maybe it's because it points back to a corrupted file on my computer?

Can I delete all the files in my W.login folder located on my local computer?  Will there be any negative ramifications?

Thanks,

Matt

Hi @mpulliam6CT22,

Thanks for getting back to me and for the additional information!

Just as a heads up we are working closely with the development team, and it seems like this issue may be limited to the Mac App Store version of Fusion 360. Do you have that version of Fusion 360 installed? If so, to test this theory, would you be able to uninstall the Mac App Store version and re-install the Autodesk website version. To do this, navigate to the directory given below:

Macintosh HD>Users>*YOUR*USERNAME*>Library>Containers

Once in that directory, there should be a folder called "com.autodesk.mas.fusion360". You should delete that folder. Once that folder has been deleted, navigate to the link provided here to download the clean uninstall utility and run it.

Once the clean uninstall has completed, you can re-install Fusion 360 by navigating to manage.autodesk.com and log into your account. Once logged in, you can select "Download Now" next to Fusion 360 to begin the installation.

Regarding your comments about deleting the W.login folder, we only recommend this as a last resort. Deleting this will delete the entire local cache and any pending uploads, so I would steer clear of doing this until we get some more information from the development team.

I hope this helps! Please let me know if you have any questions or concerns!

Cheers,

[mpulliam6CT22]

@mike.tessier

I don't see the folder entitled "com.autodesk.mas.fusion360" in Macintosh HD>Users>*YOUR*USERNAME*>Library>Containers

I'm not certain I downloaded Fusion 360 from the App Store.

Should I do clean uninstall as described on https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How...  ?

[mike.tessier]

Hi @mpulliam6CT22,

Thanks for getting back to me! I would just like to note that that directory may be easier to navigate to directly as there is no system variable "*YOUR*USERNAME*". This field should be replaced with the username that you log into the machine with. I'm sure that you probably figured that out, but I just wanted to throw it out there because I realize that I had not clarified that in my previous response.

You can still proceed with the clean uninstall if you would like, but I'm not certain that that will resolve the issue at hand. It was more so to remove any remnants of the Mac App Store installation that may have been left on your machine but I suppose we wont know unless we try! 

I hope this helps! Please let me know if you have any questions or concerns.

Cheers,

[mpulliam6CT22]

@mike.tessier

I can't find a folder called com.autodesk.mas.fusion360 on my computer.  Is that a problem?  

I've searched manually and through spotlight

[mike.tessier]

Hi @mpulliam6CT22,

Thanks for getting back to me and sorry for the delay in response!

That shouldn't be an issue - it was more just to check to make sure that you didn't have the Mac App Store version.

I have some good news though! We have been working closely with the development team to get to the bottom of this, and we have finally come up with a fix! There will be a fix coming out with one of the next updates that should prevent this in the future, but we also have a temporary fix that should get you back up and running. I'll be sending you a PM in just a minute with some instructions to work through to get this back up and running.

Cheers,

[mpulliam6CT22]

@mike.tessier

Great!  I just completed a clean re-install of Fusion360 downloaded from Autodesk.

I tried to start a new design and inserted one of my newly uploaded .step files.

I got the same error message!

Problem was solved by replacing a file on my computer (libASMkern222A.dylib) which was provided by AutoDesk.

Problem should be solved in the next update.
