Components self-exploding after creation

SketchUp Pro
1

I have an SKP file with a few dozen kitchen parts in. I’m going through the parts one at a time, turning them into components and filling in attributes such as pricing, product code, weight etc. I got about halfway through then realised that almost all of the components I had created had exploded themselves, ie. they were no longer components, or even groups, and had lost any attributes they had. The components that remained unexploded were the last 3-4 that I had created, and the first 4 I had created (see next paragraph). There was no error message or visual indication anything had changed, other than the components simply vanishing from the components tab.

I assumed a corrupted file - after the first 4 components I had got a Windows blue screen error (IRQL_NOT_LESS_OR_EQUAL). I had then rebooted the machine and continued using the recovered file which seemed fine until I noticed the above problem.

Fortunately before starting creating the components I duplicated the file and saved a backup. So I rebooted my machine, checked for Windows and driver updates, installed sketchup 2020 (was on 2019), rebooted again, and started over with the backup file. As I created the 3rd component I noticed the price attribute had auto-filled with the price from the previous component, unprompted. I cancelled creating the 3rd component, and the 2 previous components had exploded. I’ve been using Sketchup a few years now and never seen anything like this?!

Anyone got any ideas? I’m completely at a loss at the moment. If I can’t recover this it’s 3 or 4 days work gone. Thanks!

Run a memory test on the PC is a good starting point. I don’t think this is a Sketchup issue.

there is a setting to

Replace selection with component

that needs to be ‘checked’ when creating the component or it remains as loose geometry…

Yep that is checked. It does create a component - it works completely normally, with the component appearing in components tab and entity info. It’s just it then reverts to loose geometry an unspecified length of time later.

Thanks I’ll check this out.

Have you tried starting a new file and see if you can reproduce the effect in it? Since an OS crash occurred while editing a model, I’d be worried that the active file got damaged in some bizarre and subtle way.

I have now done this, and the file is behaving normally. So I can only assume the file somehow got corrupted before I saved my backup file, hence both files were playing up. Whether the OS blue screen was anything to do with it or not I don’t know.

@RLGL I ran the Windows memory diagnostics tool and this found no errors…

Thanks for your help all!
