Upload Inventor file to Fusion Version errors when using Autodesk/Fusion Connect

[mikeh2]

Just loaded Fusion and Fusion/Autodesk/Desktop Connnector and when I try to open the file in Fusion I get a versioning error.  Upload file by drag and drop into Fusion and the Inventor file opens. Fusion says I have all the updates.  Is it possible the connector is using a newer version of Fusion to generate/upload the file, compared to what Fusion actually is?  That's the way it appears.

Hi @mikeh2 ,

Apologies for the confusion and inconvenience this has caused, I understand how frustrating versioning issues like this can be.

I want to let you know that this behavior is already known and logged internally, and our team is actively working on it under the tracking ID FUS-231821, with high priority. You’re correct in suspecting that there may be a mismatch in how the Desktop Connector and Fusion handle versions during upload, and that’s exactly what’s being investigated.

Thanks for bringing this up and for your patience while we work through it. I’ll be sure to share any updates once we have more information.

Hi @mikeh2 ,

Could you please check now? We fixed the issue a few minutes ago.
Please try it out and let us know if it works. If the issue persists, kindly share the file with us.

Within Fusion I tried to open the file and I got the same error.

How would you like me to test it?  Remove the file from the Desktop Connector folder in Windows Explorer on my PC and drop it back in?  Then try to open it in Fusion?

Hi @mikeh2 ,

Create a new Folder, Upload the same Inventor file to the Desktop connector, could you please try opening again? In the meantime, I’ll coordinate with the development team and get back to you once I have more details on whether a fix for Desktop Connector is being considered.

Got the same error. 

Tried using Inventor Fusion Modelling addin and manuel saved the files in desktop connector (both as stp and ipt files). 

If downloading the file manuel from the webbrowser (uploaded from desktop connector) Fusion can open the files. 

[mikeh2]

I just attempted and opened the file in Inventor 2023 and saved to the Autodesk Fusion connector folder in windows explorer.  Then went to Fusion and tried to open the ipt and it would not.  Error read "Cannot open the IPT"  I did the same workflow with Inventor 2026 and that worked, as the IPT would open in Fusion.  1 concern I have is any file created on an older version of Inventor will have to be migrated or do a SaveAs to the latest file format.  We don't migrate inventor files unless we're doing a revision to the file as Inventor/Vault doesn't really care what version of Inventor it was created.  So with 250,000+ Inventor files (not all are CAM) this does create a concern on workflow efficiency.  Currently we utlize GibbsCAM which uses our Inventor files directly and have not heard of any issues w/ Inventor versions causing problems in terms of opening old Inventor files directly.  I started an initiative to get Fusion into our workflows across 3 divisions for several reasons, like continuous product improvements to Fusion and also the fact that it is part of PDMC.  I also see initiatives to get more Fusion/Inventor/Vault interactions more seamless.  This will make a hard sell internally if a high percentage of files we open will need to be migrated in Inventor 1st.

Regards!

@sv3JY5K Can you please restart Fusion and retry the Desktop Connector workflow afresh in a new folder location? We have made some changes that should resolve the issue you were facing.

[sv3JY5K]

Hi Sanjana

I made all avaible updates. That solved the problem. 

[mikeh2]

Yes this appears to have corrected the issue.  I also grabbed the original ipt from the year 2006 and dropped it in the Fusion Connector folder in Windows explorer and the opened as expected in Fusion.

Thank You!

The error returned today. I tried update Fusion, but i still comes. 

The function "Create Fusion Design" works. But "Insert into Current Design" and "Open" doesn't work in Fusion. 

[sanjana.shankar.goli]

@sv3JY5K Are you seeing the error after updating Fusion to 2606.1.22 ?

[sv3JY5K]

Yes - It worked for two days, then it stopped today. 

I updated Fusion to 2606.1.22 x86_64

I still don't work. 

I both tried with ipt and stp files. 

I have attached pictures of what i do and logs.

We are having this issue and it's stopping us from giving Inventor files to our CNC guys who use Fusion - I have updated my Fusion to the latest version (as of half an hour ago) and it's still not working.

This will affect our production - Please fix ASAP or give me any info you can on anything else I need to do/try.

[Rory_M]

Additional info - I am getting the file from Inventor to Fusion using Inventor's "Fusion" ribbon and am seeing inconsistent results.

Just tried with a test part:

I used the "Subtractive" button, and get this error:

Fusion can't open thursday1.ipt v1 which was persisted by version 2701.0.7 with your current software version 2606.1.22.

I then used the "Modelling" button to transfer the file and saved it under a different name ("Thursday2") in the same folder and it worked.

Tried again, using the "Subtractive" button again and saved it as "Thursday3" in the same folder and it works...

It makes no sense, I now have three files all spawned from the same Inventor source. Two work and one doesn't.

Please prioritise this fix ASAP as not only do we need to get files into Fusion in the first instance, we need to also update them to keep in track with Inventor revision changes and I don't want to update a file that's had a lot of CAM programming time put into it, only to find it no longer opens.

Hi @Rory_M ,

I Apologies for the inconvenience caused.

I’m following up directly with the development team on this regression and making sure this is treated with urgency so it can be addressed as quickly as possible. We’re taking this seriously and working to prevent this kind of issue from repeating.

Thank you for calling this out, and I appreciate your patience while we work to get this stabilized.

I just updated fusion this morning as well. We save STEP files in our desktop connector that we have ilogic setup to export from inventor into desktop connector every time we save(much smaller file size and faster updating, also we run into disappearing bodies inside of parts sometimes opening .iam files). We then open them in fusion to process our CAM so they update with inventor revisions, but every time we update we are getting the same error. 

It has basically put a halt to our production until this can be resolved. I have also attached a LOG file as well in case that would be helpful.

I'm getting the same issue uploading files from SolidWorks. I'm uploading through the Fusion website, then opening it in Fusion. About 20% of the files won't open, and returns the error mentioned above. This problem occurred before, and after I updated Fusion today. 

I wish Fusion was more reliable. It would seem I need to extend lead times to clients to account for the potential that Fusion refuses to let me work on any particular day... That's not a good way to run a business. I would prefer to be more excited about updates with new features, but in reality updates just make me worry that some features will no longer work, and my business will be dead in the water.

Started happening to us today also.

Hi @McKnight35 @mikebendick @RPierson9PJJX @Rory_M 

Apologies for the inconvenience this issue has caused, and thank you for your patience.

Please follow the steps below to help resolve the problem:

Steps:

1. Close all existing files in Fusion.

2. Navigate to
   C:\Users\<username>\AppData\Local\Autodesk\Autodesk Fusion 360\<OxygenID>\W.login

   • username and OxygenId will change

3. Take a backup of the "F" folder and Delete "F" Folder, or rename the "F" folder to "F_Old".

   • 

4. Launch Fusion, go to Support and Diagnostics, and select Clear Cache Data.

   • 

5. Restart the process by using a "New folder" and performing a fresh upload of the files.

Note: We’ve identified that when opening previously uploaded AnyCAD files, the error message may still appear.

Please let us know if you need any assistance with these steps, or if you continue to see unexpected behavior.
