File saved, edges softened

sonder · 25 Jan 2012, 22:01

I have had this happen a couple times now and now consistently with a detailed home model. I save the file, and immediately all the edges are softened. I can select edit/undo soften edges to fix it. If I don't notice it though, it remains softened.

Any fix for this?

Could any particular plugin be contributing to this effect?

Not from what I can tell. I have zero plug-ins that deal with softening edges.

Well I was thinking maybe one of those builders tools, with a suite of special tools in it. Say, like a roof tool or building component tool for beams and such.

It's a known, and very annoying, SketchUp bug. It even happens when you minimize SU and restore it.

It only happen to selected geometry. And it happens when SU is busy and stops responding for a moment. When the window then refreshes the Soften Edges function is bizarrely activated.

For this reason alone I constantly deselect in order to avoid inadvertently softening the model. If you see it happen you can undo the operation.

Also never leave the 'soften/smooth-edges' dialog open when you don't need it, if it becomes the foremost dialog [even when rolled-up?] then selected things can sometimes be unexpectedly softened by it inadvertently.
I suspect it might also be graphics-card related: I get this issue rarely, if ever...

I do not get it either which makes it even more weird (why would a certain graphics card trigger a modelling step that can clearly be undone?).

I remember your issues however, TT.

I'm not sold it is GC related as it only recently started happening on three of my latest models. I was able to undo before closing. I don't have the soften dialogue box open either. I will verify the deselect before saving. I think that makes sense, because on one model yesterday, I tried saving three times in a row and each time it softened the edges. I then tried using another operation before saving, which resulted in deslecting. It then saved successfully. If this is a known bug, I would definitely place it fairly high on the list.

Yes, it is a known bug. But it was one that was risky to fix which is why it hasn't been done yet.

Hopefully a fix comes about. At any rate, your recommnedation of deselecting before saving appears to work every time. Thanks!

If it seems to be a glitch with having something selected when you save, then it's possible to have a ModelObserver for onPreSaveModel etc to make the selection into an array, ensure the selection is then empty before there is a save and then another one for onPostSaveModel to restore the selection as it was ? Also App observer to ensure 'new' SKPs have the observers...
Try putting this into the Plugins folder, and restart... and see it if helps [you'll need to deliberately save with a selection made...]TIG-SmoothingSelectionGlitchObservers.rb

No, not save specifically. It's after the SketchUp UI has hung for a while - (such as during save, sandbox tools or other operations). When the UI becomes responsive again the SU window refreshes, you might see some flickers of the toolbars, windows etc. It is then the Soften Edges function is for some mysterious reason triggered. As a result, minimizing and then restoring also cause this issue. I first noticed this when my terrain meshes got all strange smoothing after I'd restored a minimized window.

So because of that I keep deselecting very often. (Ctrl+t)

Odd. I saw it for the first time today.

sonder · 28 Jan 2012, 03:22

I'm curious if model size has an impact. On mine they are all around 30M in size where this occurs.

thomthom · 28 Jan 2012, 11:42

The longer it takes to save, the more likely it is that SU will freeze up for long enough to cause "white-out" and then trigger it.
I see it also when I use Sandbox Tools to Drape geometry. If it's on large geometry, which cause SU to "white-out" while it works, Soften Edges will also trigger then.

I think this happens only on Windows.

Dave R · 28 Jan 2012, 11:51

The file it happened on for me is 629 Kb.

TIG · 28 Jan 2012, 11:53

Does this occur irrespective of the Smooth/Soften dialog being open at the time ?

Yes.

Dave R · 28 Jan 2012, 11:55

I don't believe it was open in my case. I don't normally keep it open and I didn't have any reason to use it on that model.

thomthom · 28 Jan 2012, 11:57

As I mentioned, it happens whenever that SketchUp window need to refresh, either after "white-out" from processing, or after restoring a minimized window. There are no single triggering action and can happen on any kind of model.
