Your profile says you might be utilizing SketchUp Free (net). There gained’t be a.skb backup file however you need to be capable of discover a earlier model of the file in your Trimble Join storage if it has been saved beforehand.
Sorry, I clearly checked unsuitable choice, it’s 2020 Professional SketchUp.
I’ll change it in my profile.
Thanks for updating it. Do you may have backups disabled in Preferences? There needs to be a .skb file in the identical listing because the .skp file. The place are you saving your SketchUp information to?
That’s what I ment, once I mentioned “most important one”. I’ve discovered that .skb file in the identical listing, however it’s currapted too.
I’m saving it to exterior onerous disc. 
That’s in all probability the explanation for the corruption. No less than that form of factor has been problematic for a lot of customers. The recommendation is to say to an inside drive and replica to an exterior drive afterward.
Hopefully Colin will be capable of retrieve at the very least the elements and supplies for you.

Sure I perceive, now. What do You assume, is there any sense to somebody verify my file? I can’t clarify this … I’m utilizing SketchUp from model 4, and in any case this years, I made newbies mistake. 
I believe it’s in all probability value having Colin have a look at the file to see what he can discover together with his magic wand but when it’s one thing you want quickly, I’d even be interested by beginning over and making ahead progress. Very possible you’ll be capable of redo the mannequin extra rapidly than you made it the primary time.
Good luck and also you’re welcome.

The result is identical as the sooner instances. This file has elements in it, and supplies, however the scene will likely be empty. It’s essential have a look at the In Mannequin elements and see if there are bigger elements that can aid you to rebuild the scene.

Colin, Thank You verry a lot! You saved many hours of my work and product growing.
On first sight, I believe InModel, are all elements, however I’ll test it out fastidiously tomorow.
Anyway BIG THANKS as soon as once more.
@colin I’ve run into the same subject to all above, any likelihood you’ll be able to check out my file to see if any of it’s recoverable?
Your file has the identical scenario as one other file somebody posted yesterday. I didn’t but hear from the developer, however I added your file to the bug report.
Thanks @colin ! I’m assuming the bug is said to saving on a community?
Almost certainly.
I can’t recall ever seeing a report on the discussion board the place this occurred when saving to the native onerous drive. It all the time entails saving on to the cloud, to a networked or different distant drive, to an exterior drive, or to a folder that’s routinely synced to a distant server.
Evidently there could also be a couple of type of occasion that causes the corruption, because the varieties of injury seen are diversified. Some information have misplaced the mannequin database, however retain their elements and supplies. Colin can often get well these elements and you’ll rebuild the mannequin contents from them (with some effort, however lower than beginning over utterly). Different information have had giant parts crammed with rubbish or zeros and usually are not recoverable.

File corruptions typically could also be associated to being saved on a community drive, however for a case like yours, you probably did an motion in SketchUp that led to there being objects that had duplicated ID numbers. We’re making an attempt to determine what motion persons are doing that would result in that downside.
