Changes are (randomly) lost

kschepens — Fri, 06 Mar 2020 10:49:48 GMT

Ok, this is quite hard to put my finger on but this seems to be occuring quite often.

I occassionally get consistency errors between board and schematic, even though I'm quite sure I have all documents open in Fusion 360 all the time (I've learned from previous issues). When I check what the error is, I notice that it was due to a change that I made that seems to have been lost (or lost partially, in the schematic only). I'm pretty paranoid when it comes to saving so I try to save as often as possible and I have not a single recollection of Fusion 360 warning me to save anything before closing the program.

This worries me a lot!! Do I have more changes that are lost but I'll never find out because they don't cause consistency errors???

I realize this is all very vague but I'd like to know what could be causing this.

I am having this issue also, the changes i did was all lost even though i saved those.
one time i lost 2 hours of work.

Why remove the Eagle link even though the fusion electronics is not ready?

I have had this same problem several times now. I thought the issue would be resolved by only saving from the project file (never save directly inside schematic or board) - but I just swapped a bunch of parts from 0805 to 0603 packages, saved the electronics project, waited 10 minutes, closed fusion.

When I reopened fusion, the project file shows the right screenshots, but the schematic and board, while on the right version number, have the 0805 packages so it lost all my changes.

Hopefully this can get fixed soon, I absolutely love the new workflow possibilities with everything being in Fusion now!

Hi bschochHYCHE,

Thank you for joining and participating on the Forum. Just wanted to let you know the team of developers are monitoring the forum and looking into this. They will do their best to find a cause at the earliest time possible.

With warm regards,

Today it happened again. After coming back at work from the weekend, I noticed multiple changes from last Friday were lost and there were again inconsistencies between board and schematic.

THIS IS A VERY SERIOUS ISSUE!!! If I cannot trust Fusion 360 to actually save my work, I cannot rely on this software!

the latest update did not fixed this issue.

Latest update did not include fixes for PCBs. There are massive dependency issues besides the crashes, so do not expect a solution very soon. Disclaimer: I am not from Autodesk, but have handled similar projects before.

I've had the same issues and have been in contact with a couple of people from the Fusion team, the latest communication from them is they have found the cause and are working on a fix.

A temporary solution that was suggested to me may help; Take this with a pinch of salt - it worked for me earlier today but failed just now, the minor change I made in the schematic to allow me to save - didn't save, the 2DPCB and 3D PCB did save.

When your done working on your project, go to each file (SCH, 2DPCB, 3DPCB) and make a small change, moving a component looks to be enough, this should produce an "*" at the end of the filename in the tab, then switch back to the main project window and hit save.

In the case of the 3DPCB you'll need to forward the changes from within the 2DPCB.

Make sure you have the data panel open whilst saving and watch for the previews to update and assign a new version number. You can also expand each one to make sure the latest file is the most recent save.

I do not doubt that the "shifted component" problem will be solved soon, but not the dependency issue. I have dozens of copies of layout and components around that I can only get rid of by deleting the main project, and making a copy of the library, relinking.... forget it, you cannot edit the library link field of a component. And "used in" does not give me a hint where this component is used.

These are the major issues where I believe a heavy rework is needed. It is inherently difficult to get things right if you really want to keep the whole history - and I greatly admire how got this to work so beautifully in mechanical design.

Hi @dieter.menne

Apologies for the confusion I was referring to the changes lost whilst after saving issue. I hit "reply" on the wrong post.

I agree though the dependency issue is another minefield itself! I have a "rubbish" folder that I'm dropping things in when it all get's too messy, but this isn't indicative of "keeping ones house tidy" more "sweeping it under the rug".

Fingers crossed they iron out the issues because it has such potential!

Hi Guys,

All of this is being worked on with the upmost urgency. Thanks for sticking with us.

Let me know if there's anything else I can do for you.

Best Regards,

I have started using a slight variant of this approach and so far been ok..

- make changes to schem and/or pcb

- save the schem and pcb using the save button on the schem and/or pcb window itself (not electronics procject!). This gives me a saved version for each file just in case anything goes wrong. I also make sure board and schem are consistent.

- next, I make trivial changes on both the schem and board (move a component in schem just slightly, move a gnd plane line slighty) so that both schem and board have unsaved changes

- finally, save everything from the electronics project window. If the save works as expected, everything gets versioned up one, no problem. but if any work does get lost again, at least I have a previous version 'hard saved' for each file I can restore from.

Anyway -hope that maybe helps someone else, it's about the safest workflow I have found so far at least.

I've had the same issues when the schematic. When switching back to the PCB Document the board and schematic are missing updates from the schematic.

I've had this happen several times, and the real kicker is that "saving often" doesn't seem to make the situation better. I spent hours today working on a PCB layout, saving very frequently. I closed Fusion 360, then when I re-opened the design, several versions of changes were gone. All the version numbers were still there, but opening the last several versions all revealed the same, outdated data.

All I can think of for now is to periodically close out of Fusion360 and re launch to make sure changes are actually being synced. That will at least minimize the loss when something does go wrong.

I've specifically made sure to save correctly, too. When I need to save, I go to the main design file and save from there.

Just wanted to throw another testimony up here that this is happening to me as well. I'm saving frequently from the design, everything was in sync when I left the project. Now, opening it up 2 days later, despite the version labels all being there, the schematic appears 4 or so versions back and broke all connection between SCH and BRD.

This is gonna take me hours to get back to where I was.

EDIT: Sorry, just figured out that I should have replied to the top post rather than the one above me. Can't figure out how to delete this post, so it'll just be a mistake forever 😛

Count me in as another seeing this. Went to use a design that another team mate spent all day yesterday updating. Design file and board file show V32, schematic shows V18. Literally hours of work missing. I went and looked at a test board I made in January and haven't touched since. It's just a board with a funky shape and two components with no connections and no traces. That too is screwed up even though no one has even looked at it since January.

We're also completely thrown by the years of muscle memory that says you should be able to hit ctrl/cmd+s from any tab/window, be it schematic or board or design file and have all of those save as a group, but it doesn't seem to work that way in fusion like it did eagle. More than once I've burned myself just hitting ctrl+s on a board window and completely breaking the whole design because it saved one out of sync with the other.

Hi Guys,

We hope to have a hotfix out shortly that should address this. Our devs went through a lot of code to figure out what happened. This one has not been easy to fix.

Let me know if there's anything I can do for you all.

Best Regards,
