Arrange feature crashing program

[ruga666]

Hey everyone,

Just watched a webinar with our friends from NexGenCAM about the feature.  I fooled around with it a few months ago when I was given permission to use it in a BETA version.

I'm following the exact steps to arrange parts, I only have 9 small misc. size parts at 3/4" thick and every time I click OK, or if the the Preview button is selected I get a small bar in the bottom right corner of my screen that says 'Compute Started' and nothing happens and the program crashes.

Did not have this issue a few months ago when I was using the same feature.  Anyone have any advice as far as why this would be happening?  It appears that the program is up to date although I do see a March 27th Fusion 360 will undergo planned maintenance reminder.

I'd like to add, bravo to the team working on the Arrange and Nesting features in Fusion 360.  It's come a long way since the last time I was messing around with the feature aside from it crashing my program ha!

But has anyone out there having the same experience?  Or is it just me, and if so is there anyway I can re-install it somehow.  I'm using a good machine and I was just doing it a few months ago so I'm not sure why this would be happening?

Thanks

If you can share your model, please do, so we can try it here.

Also, was there a crash report, if so do you have the report ID, or the e-mail with which you submitted it?

Thanks,

Nope no crash report, just loads forever and nothing happens

Here's the file - Wasn't kidding when I said it was pretty basic

Thanks

Thanks. Any chance you can share a video of what you're seeing? Also, when that happens, can you check task manager to see if Fusion360.exe is taking any CPU time? (or some other process)?

Thanks,

@ruga666 ,

Thanks for reporting this and sharing the model. In the span of last three weeks, you're the second customer reporting this behavior, but we haven't been able to reproduce this issue so far. I just tried it with your data and it arranges fine for me - no hanging or crashing.

What boundary method did you select to arrange the components - plane/sketch/face?

I've created a new ticket for this post (TRUNFSN-2647) and linked it to the existing ticket (TRUNFSN-2620).

Can you please share your log files? - https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How...

p.s. - Thank you for the kind words of appreciation. I will be sure to pass it onto the teams involved.

I apologize for not being able to respond sooner been so busy.  But I'd like to give you all an update and I think I found what the bug is that's causing the crash.

So I'm constantly taking AutoCAD drawings and laying out 2D CAD on a 5x12' "table" which is the size of our CNC bed.  I find it much faster and easier to do 2D stuff in AutoCAD and then export the DXF and import it into Fusion 360 to model and program.

This morning I had some free time and I said hey let me get to the bottom of this, I opened up the Fusion file I had previously posted to the thread - went through the arrange steps, and it worked!  And I thought to myself, great must've been the new update that fixed whatever bug or issue I was having.

Open new fusion file import DXF, turn my sketch into a 3D model go to use the arrange feature - program crashes.

So I then open new fusion file, import DXF turn my sketch into a 3D model and then export it as a fusion file to my desktop. Re-open the file, go to arrange - it works.

I then create new file in fusion, CAD a couple of squares extrude them go to use arrange - it works.

So lastly I create a brand new DXF file in AutoCAD, import it to Fusion 360 go to use the arrange feature - program crashes.

There is something going on with arrange feature and using an imported DXF in Fusion 360 to arrange and that's all I know.  Unfortunately I do this literally all day long and am constantly importing sheet good DXFs.  Anyone having the same problem now that I've kind of narrowed down what is causing the crash?

Any info would be helpful, thanks

Just curious if anyone out there has looked into the issue, or has anyone noticed the program behaving in the same manner following the DXF import steps mentioned above?

Thanks

@ruga666 ,

Thanks for sharing the details. The QA team has replicated the hang issue on one of the computers. Issue is being fixed now and will be included in the next update.

Background: Developer mentioned that it is being caused by loading of incorrect Qt dlls. Apparently there is another application on the offending computer that uses different Qt dlls and the application automatically added its path into system environment variable - 'Path'. When the nesting algorithm tries to call for the Qt dlls, the incorrect ones are loaded thus resulting in a failure that Fusion isn't aware of and eventually results in the hang. In your scenario, it might be that AutoCAD is loading certain Qt dlls that are a different version that what is needed by arrange in Fusion 360.

Temporary Workaround: Check if there is any path defined in the PATH system environment variable that may contain other version of QT dlls. If so, remove them from the system PATH environment and try again.

Let me know if that helps.

@ruga666 , i am trying to replicate the crash issue, you mentioned about import DXF to Fusion, then do Arrange, Fusion crashes. 

for Import DXF, do you run the "insert DXF"(attached a snapshot), or other command? 

and is it possible to share the dxf file you used when crash happens? I tried a simple dxf with 3 rectangles, and using insert DXF command, and then do Arrange, no crash in my pc.
