Crash on STEP export

[furmanr]

This is a wierd one...

Fusion started crashing on me when I export to STEP.

Firstly it started with very large assemblies and particularly with a simple design with a modeled thread, which I zeroed out

immediately - after removing the modeled thread, the export was fine, but it went downhill from there. 

More and more STEP exports finished in crashes until it basically does this on every single step export now,

say 99% of the tries i take.

Wierder still, export to IGES works without a hitch - and after re-uploading the IGES as a new design, the STEP

export magically does it's job again for the imported IGES.

I did a clean re-install of Fusion and it didn't work, as if the bug was somehow tied to my account (tried a different

account, same fusion design on the same machine, export works fine). Another bug that seemed to be tied to my account was when a

couple of months back Fusion didn't want to start in offline mode (it displayed an error on launch, stating it needs

an internet connection) - and a clean re-install also didn't work.

As for now I'm relying on the export-iges-then-import-and-export-as-step method as a quick fix, but it's an

unnecessary step (get it? step? 😄 ) added to my routine.

Any ideas?

Hi @furmanr,

Oh no! That does sound like a weird one. Do you have any of the CER numbers from the crashes, or did Fusion 360 hang until you had to force quit? Also, are you able to export your designs as STEP files when you try from A360?

Sure enough, as soon as I wanted to export something to copy the CER, everything started working fine

I tried the very same designs that caused crashes yesterday and the weeks before... and also a 3000 body assembly from which it

produced a 100MB+ file without too much fuss.

Sometimes you just have to scare them I guess... I will post the CER numbers to this thread as soon as it starts crashing again 😉
