OBJ Export not currently working

Usually when I need to export a .obj from F360, it takes about 15 minutes for the download link to hit my email inbox. It's a lot longer than I'd like it to take, but that's tolerable. Sometimes it takes quite a bit longer... an hour or more. 

 

For the past 16 hours I've been trying to download a .obj of a model I've built and it's not working. I've tried downloading/exporting it 4 times over the past 16 hours or so. It's a large file, but shouldn't take this long. It's making it very hard to hit deadlines. 

 

Thanks for your help,

Hi @willgibbonsdesign,

 

Thanks for coming over here from Twitter. I've gone ahead and requested from A360 a download link to the Fusion archive. Let's see if this one comes through - this will be a good indication as to what might be going on. Feel free to take down the public link as well. I'll let you know shortly if I receive the file/what might be going on. I have a feeling the file is failing translation so I may have to get that team involved. 

 

Thanks,

Thanks for your help. This exact file/design was working up until last night. I was testing it incrementally... I patterned a couple components and tried to download again and then it never happened. Am interested to see what ends up being the issue. 

 

Thanks.

Hi @willgibbonsdesign,

 

Just wanted to give you a heads up that I am still working on this. I tried manually exporting each component, and they all seem to work fine hinting that there is no issue there. I also turned off the design history so had the model in direct modeling and tried to export - but no dice there as well. I'll keep experimenting a bit and see if rolling back the timeline to before the changes works. I've also escalated this to the translation team so they can have a peek as well. 

 

Thanks,

Actually, I tried that same thing with a solid model in A360 yesterday. I've not received a download email yet. This was not a large model, only 6 components with a bit more complex geometry, but nothing outrageous.

 

The other user I was trying to help also reported very long wait times for .obj exports.

 

@willgibbonsdesign The .obj export as far as i know also creates triangulated mesh files. You might as well go ahead and export the entire design as a .stl and convert that .stl to a .obj using a sub-d modeler. I use a blender for these things 😉

Hi @TrippyLighting,

 

Thanks for posting. Two quick questions - was it a distributed design? Also, were you exporting to OBJ format or a different one?

 

Thanks,

@James.Youmatz Nope, single self contained design into .obj format.

Thanks. Re: .STL export. I can do that. Just don't want to (of course) but great to know of this workaround when I'm in a pinch.

@James.Youmatz Thanks for the update. How about today? Anything? I tried once more... still waiting.

Hi @willgibbonsdesign,

 

Unfortunately, nothing positive to report. I keep trying things, but I too am unsuccessful in this export. I even tried rolling back the timeline, saving the file, and then exporting to see if it was tied to certain commands. Still unable to get this export working. I think at this time, I need to turn this over to the development team for further analysis, but my suggestion in the meantime (if possible) is to use the STL format to continue your workflows. I will keep working on this, but I do think there an issue with something in this file and the combination of our OBJ translator.

 

Thanks,

@James.Youmatz This is super unfortunate. I've been chipping away at this project for over a month now, and to finish modeling it and literally be unable to get my data out of Fusion 360 is unacceptable. I'm blown away this is an issue. I've tried the .STL export as suggested. It doesn't work. Sure the data is exported, but as one body that I can do nothing with. I used the KeyShot plugin to send it to KeyShot, but not every part comes over and what does is very low-poly.

 

Can anything be ruled out or narrowed down? I can't just abandon this project. Is there anyone else more technical who can look at the file and determine what's happening? Can any local resources get it exported a an .obj?

 

Data export is highly crucial. You can't say you're a CAD application and then have a handful of features not work for distributed design... and then not allow users to export locally... if you make me use the cloud to do so... it ought to work. I was exporting this file every day to check it as I went along. It literally stopped working the day before I posted on the forum 2 weeks ago. I was getting exports that very day. I find it hard to believe it just got corrupted.

 

Any further suggestions? I'm focused on finding a solution, but will need to abandon A360 and strongly discourage other professionals from using it due to glaring issues such as this. It's too much to lose an entire month's work for nothing.

Hi @willgibbonsdesign,

 

Sorry about the delay in getting to you. I just heard back from the team regarding the issue. It turns out this is a limitation of the exporter. Unfortunately this design includes more than 30K meshes, which is too big to  export as OBJ&FBX for Fusion.

 

While I could successfully export the design as an OBJ in a more powerful workstation (40 core CPU, 32Gb memory), the export still took more than 2 hours.  The machine type is  4 CPU, 7.5Gb memory which is much less power than my workstation, and as  the current timeout setting for Fusion cloud translation is 8 hours, this is why the export failed. 

 

I've gone ahead and sent you a download link to the OBJ file in the meantime.

 

Regarding future use cases of this, I have started this conversation with our product mangers for this field, as well as with the developers to hopefully understand the needs a bit better, so please feel free to comment your thoughts!

 

Thanks,

Hi James, 

 

Sorry for this delayed response. I had a few very busy travel weeks and this slipped through. I'm pleased to see that you've managed to figure out the WHY behind the problem. I can live with this as a solution because it's something I can work around if needed. I highly encourage this be documented somewhere so others don't deal with this roadblock. 

 

Thanks for seeing this through.

Sadly, Will, THIS is the documentation.  😞
