Issue with F360 hangs - Random but un-recoverable

[Anonymous]

The past couple of days I've noticed that Fusion has been hanging a lot on even simple operations, and when it does so it cannot recover (must force quit, sometimes losing recent changes).

The first time I ran into this issue, I was working on an STL file, trying to combine faces to bodies.  I suspected that there were simply too many faces and it was causing a problem.

Now I'm running into it on a Fusion model, this current time just trying to undo a sketch (that should be a fairly simple thing - the sketch was a simple circle).

Hi @Anonymous ,

The STL situation makes sense - as that is a computation heavy operation, but the undo does seem strange. How long do you let it go before force killing it? Does it ever recover?

Thanks,

Hi James,

Well, I successfully worked for a few hours last night without any hangs at all.  The time before I posted this, I let it run for easily an hour before killing it (in fact, walked away from the computer to work on my printers, it was probably closer to 90 minutes).  Came back and the app was still hung and still using 100+% CPU.

It has been other functions that have hung it as well.  Once it was after hitting ESC to drop out of an extrude.  Doesn't seem to be any rhyme or reason to the cause, but when it happens there definitely appears to be no recovery.

@James.Youmatz - there definitely does seem to be a memory leak, likely on undo, but I cannot say absolutely for sure.  New design I've been working on, keep having to close F360 and reopen it to be able to work.  The one thing I noted was that Activity Monitor was showing F360 using 3.2GB of RAM.  When I closed my project, it only went down to 2.8GB.  So I closed the app.  I reopened the app and with no project open, it was using ~500MB of RAM.  After opening my project again, it only went up to 875MB.

I'm running MacOS Mojave 10.14.3 and currently have Fusion 2.0.6263 installed.

I'm not very efficient with Fusion yet, and I'm sure that might be part of the problem, but a 2GB gap in the same project is pretty wild.  The vast majority of what I've been working on today has been sketches for future cuts and drills.

I have the same problem. I'm sure it's a memory leak.
