MAJOR ISSUE: July 2016 has made Fusion unusable - Please Help

[gavriilklimov]

So I am creating another topic since another one I made seemed to have gone completely unnoticed from "Community Managers" and Fusion360 employees.

Yesterday night (Friday night) Fusion decided to automatically update to the last version.

Up until that moment everything was fine. After the update, I CANNOT use Fusion. I emphasize this again, I can't use Fusion to work anymore.

There's 3 cases:

1) Creating a new scene and working in a new scene

2) Working on a previously created scene

3) Working on a previously created scene with mesh-bodies inserted in them (Imported OBJs in the scene)

In order :

1) Case 1, Fusion "works" OK but with MAJOR lag and performance issues. Everything which used to be very smooth now lags. My viewport performance has been significantly affected. Every operation now takes longer, a simple boolean takes x2 as long as it used to calculate.

2) It is absolutely IMPOSSIBLE to work on previous work-files. I have tested this on DOZENS of scenes I was working until yesterday so please do not think this is "scene" specific. I have tested it on over 30 scenes and they are all the same.

To give the best example, if on a flat-surface in an older design I create a round sketch

and I push-pull it down to create a boolean. From this step to

This step. Takes about 10 SECONDS. Whereas in the past it was no time at all and was instant.

Upon pushing "ENTER" to let Fusion actually perform the cut - the operation starts to calculate its result.

Based on the scene (I assume how big/small it is) this operation now takes anywhere from 10 minutes to 50+.

In the bottom right corner I can easily see this dude going from 1 and after minutes "2".. and so forth.

As you can see I absolutely can't work on anything with this performance.

3) Case 3, a case in which an older scene had a body mesh inserted in them.

The thing that stands out right away is that now where I inserted the OBJs in the scene now it's on the timeline.

These scenes have even WORSE performance than scenes from case 2. Practically ANY operation I perform takes Fusion x50 the time even from the already heavily crippled old work scenes.

Example: In a scene which up until yesterday evening was PERFECT - now I fillet a box with a sharp edge.
Upon  performing the fillet the bottom right of Fusion goes:

and

and

and after about 1 full minute, it's at 2% 🙂

a minute after it's now at 4%

after 30 mins it's now at 17% so I force quit Fusion.

Fusion is absolutely unusable, straight up I can't work on anything. I am baffled that this update has caused this major issue.

I have tried to clear the cache from the ? menu on the top right, I have tried to re-start the PC and run nothing other than Fusion.

I have uninstalled and re-installed Fusion.

I would like to be able to roll-back to the previous Fusion version ASAP since I am worried it will take you guys too long to figure out what's wrong, and I will be stuck without being able to work.
Could someone tell me how I could roll back to a previous version while someone can look into this MAJOR issue that occurred with the last update ?

Hey Guys,

For uninstalling softwares, use this program Revo Uninstaller. It cleans everything.

I have used this program for few years now, and it's brilliant 🙂

Cheers / Ben

[daniel_lyall]

have you tested it on fusion

[Beyondforce]

No, I haven't tested it on Fusion, but I have used it on Inventor, MS office and many other softwares.

Hi,

The problems listed here are very concerning, however they are not something we have encountered in our internal testing. This suggests that it could be linked to specific modelling approaches or to specific system configurations. A workflow that I saw mentioned in the discussion was working with an inserted OBJ file, is it possible that others who are experiencing the issue are also working with inserted meshes ? (The most recent update added a Mesh Workspace as a preview feature, which may be related to the new behavior).

If anyone would be willing to share with us a model which demonstrates this problem, it would definitely accelerate our ability to diagnose and resolve the issue. This can be done either by exporting in Fusion Archive format through our web portal or by creating a public share for the item (and adding a password). If possible please forward files or details to me at matt.pooley@autodesk.com.

Hi Matt,

Please check out my last post. I have also attached the file that I was working on. Something is wrong with the basic functionality of Fusion 360!

We have been looking into this issue last night and this morning.  We sincerely apologize for any disruption in your workflow.  Here is what we know now:

1. The issue seems to be limited to models which contain imported mesh bodies
2. When opening older models which contain meshes, the model is put into a "dirty" state.  This is the bug,  This state requires the design to be recomputed.
3. When you start any modeling operation, Fusion will do this recompute.  This is what brings up the green "progress bar" in the lower right hand corner of the screen.
4. Once that first compute is finished, the model should be in a good state again.  From my very limited testing, performance has not changed from previous releases

So, what I would recommend, until we can get a fix, is:  Open models with imported meshes, and do a Compute All:

Then, save the model.  You should not see any degradation in performance after this point.  If you see otherwise, let us know.  We are working on a fix that will prevent the dirty state.

We appreciate you all helping us debug this by sharing your designs with us, and we appreciate your patience.

I will test that with two designs I have.

Hello Jeff -

thanks for replying -

You mentioned that the issue seems to be limited to models which contain imported mesh bodies, however, I have the same behavior in scenes that had OBJs imported or that had nothing imported at all. As I wrote in the very first post when I created the topic, I noticed a slight difference.

Models that had the OBJ imported have even worse performance, however, models that didn't have anything imported as almost as bad.
So far the difference I noticed is that models that had nothing imported can take up to 25 mins to perform a simple task, whereas model that had an OBJ in them can take even more than 60.
So they're both compromised.

As far as your solution: I have clicked on "Compute All" and tested it on a model, not even one of the biggest ones I have, rather on a smaller sized model.

After 27 minutes it's still at 3%

As you can imagine, it doesn't seem like a viable option. I will likely test to click "Compute all" and leave it on overnight since it appears it will take several hours.

Even if "compute all" takes overnight and then makes the model OK, it doesn't exactly seem a viable option, imagine models in which it might take longer than overnight, and on top of that, I'd have to do it for literally hundreds of models.

I have shared two models with Matt whom wrote above. I can share two files with you too if you are interested in testing it out. Feel free to give me your email address.

By the way- as far as "saving" and "closing" goes, that is also heavily affected. When clicking on the little "X" 

To close a file, now Fusion takes anywhere from 45 seconds to 5 minutes to close a file, whereas before the update I think the longest I've ever had it wait was 10 seconds for big files.
Saving is the same, if I perform any type of change to these scenes where the performance is corrupt I am absolutely unable to "Save" the scene.
Clicking on save simply triggers Fusion to freeze.

I have let it "save" for over 2 hours yesterday few times and was always forced to force-quit Fusion because it's stuck.

@matt.pooley

Hello Matt-

thanks for replying.

First and foremost, I have sent you an email with few files.

Secondly, just to mention here on the forums the same stuff I have mentioned on the email; this issue is NOT limited just to models that had OBJ imported in them.

This effects every previous work file, whether there was an OBJ inserted or not.

I have sent you two models, one where there was an OBJ inserted, and one that had nothing in it. They're both compromised and I can't work on either of them.

If you read the reply I just wrote to Jeff above here, doing the "compute all" doesn't seem like a viable option either, after 30 mins I am still at 4%. And this is a pretty simple and small model. Can't imagine if I did compute all on a bigger one. With that said, I haven't reached the point where the compute all has finished and I can test if the performance is actually not compromised, but if a model finishes, I will post here and update everyone.

Thanks

@jeff_strater

Here is the problem for me, 90% of all my work has imported mesh data. I tried the recompute all and performance is still terrible. 

[daniel_lyall]

@jeff_strater have a look at the graphics cards most are nivida that are having problems 

[cekuhnen]

@daniel_lyall Why should the graphic card be responsible for CAD operation slowdowns?

The screen refresh rate when panning zooming is very fast. 

@jeff_strater

opening an 80 MB file takes minutes - pressing re-computate takes ages - adjusting a feature takes ages - it is still computing 25 minutes later - this is not a workable solution.

Fusion currently uses a complete core - as it looks the computate all is not multi threaded - can this be multi threaded?

One hour still doing the computate all

[daniel_lyall]

@cekuhnen I have seen it happen on other programs A amd card will be at 30% a nivida will be at 80% same size cards and computer specks same program and file running using the same testing programs. it was just as bad with a bigger nvidia card what was on a computer with 16 gig ram and a ssd. compared to a computer with 6 gig of ram and a 1 tb hard drive.

it turned out the program had all the up to date graphics programing on it, what was the same for what AMD cards where at the time, the nvidia cards were behind in graphics programming, it was retested by a IT engineer, it was over my head why it was playing up but that was the reason for the differences.

I played with one file in the new work spaces and it was fine it was all ready in fusion 

I just imported one in and it's fine no lagging fusion is working fine.

if I turn the color sketch geometry preview on fusion tanks then, with it off it fine

[gavriilklimov]

I don't quite understand what you are saying in your last post Daniel, however, this performance issue is not limited to either a single PC rig, nor a GPU manufacturer.

Class here has an AMD card (just like most OSX users) and has exactly the same problem I have where the performance is so bad it's impossible to work. I think this problem affects equally NVIDIA and AMD users. In fact, it even affects NVIDIA GTX and NVIDIA Quadros which are very different cards.

Also, Claas is right, the viewport is not slowed down, when I open a file I can move around it very quickly - in fact, that's the only thing that works OK.
It's when trying to perform any operation which Fusion straight up dies. I can't even save or close a file anymore because Fusion freezes and dies.

[daniel_lyall]

@gavriilklimov yes well I am not having these problems at all it was just a idea as I have seen a program tank and the only differences was the graphics cards used.

the reason for me that I am not have this problem is I have turned the sketch color preview off, if it's on it's bad have you turned all the preview stuff off.

[cekuhnen]

@gavriilklimov

I actually have 2 GTX 970s installed because I use CUDA for rendering 😉

[cekuhnen]

The mesh system is currently unusable because of scale and placement issues agains when you need precise positioning and maintain obj or stl file based original position.

@jeff_strater

I am curious why only few people howeve have such a dramatic performance hit rendering their files useless. Maybe most have small files only.

maybe this is not hardware related at all but that fusion treats the cad data differently and those massive files that worked well before and no ruin fusion not many users have.

maybe for internal stress testing use equally big files that killed fusion now in the future.

[gavriilklimov]

@cekuhnen

we don't know how many people are having this performance issue, so not sure if you can say "few people".
There's such a small sample of people that post in the Forums compared to the entire Fusion user base.

Also, so far even within the forums you can count at least 6 people with this issue.

Lastly, this performance problem affect every older file, no matter its 'size', I have this problem with models that are literally a box with few booleans.

[gavriilklimov]

@daniel_lyall

Hello Daniel -
I also have had that feature turned off since I've started using Fusion and it hasn't changed in the recent weeks.

[cekuhnen]

@gavriilklimov So basic files can have that problem already?

I noticed something else - while not doing much to nothing Fusion was using 300% CPU time of my 8 core system.
