SketchUp messes with my geometry!

I think I have seen it mentioned here before. I am not sure, but it might have been a plugin that goes awry when Autosave kicks in. The “not undoable” bit points also to that direction.

That’s what I think also. I have a strong feeling the mess happen while I was doing the movement and the autosave kick in. I increased the rate of auto-saving at 3 mins, and by doing that increased my chance of this happening.

I don’t think the answer is in the file Dave. But thx anyway.

I looked at the second uploaded file. There are no components in the upload. It is all loose geometery.

Added the word second

The first one has a component.

Here’s the original file, as a component:

Very interesting. I do have VRay… It’s installed but it’s disabled in Extension Manager.

I’m not sure Vray has been definitively blamed but it sounded like the same symptoms.

But it’s kinda confirm the source of the problem: The auto-save.

I remember in the old days. Autosave was making my autocad crashing and I never seems to find a fix to it.

oh, dear!!! it happens again.

I had an experience with another extension causing issues even as it was disabled in the manager. complete removal was the only solution.

Cool avant-garde architecture! Your design is improved! :rofl:


This comes up quite regularly, there are many threads about it but they are hard to find due to the unusual nature of the issue and therefore the strange thread titles of people trying to explain it.

Basically it has been tracked to autosave reacting to a selection of extensions. No one extension has been pinned down as the culprit, seems like it can be a mix, the only common denominator is autosave.
Turn it off and get in the habit of manually saving regularly. Having autosave kick in right in the middle of something is a pain anyway as it slows things down. Much better to save regularly, once you reach a specific point, before you use a complex extension, whenever your fingers are near ctrl s.


Yep, just happened to me twice in about a half an hour just the other day. I’ve been seeing this for years.

I also used to have this awful problem and I think (from the very vague memory I have) it may have been related to my 3dConnexion SpaceNavigator.
Are u using one of those ?

I have not been using one … yet. I just bought one, but not installed yet.

To the best of my knowledge the 3d connexion has not been associated with this issue.
There was a 3d connexion driver at one time that caused sketchup to crash if you tried to orbit with the move tool over a vertex.
And there was a run away memory error with mac that was problematic.

Yeah… memory issues in the past, but 3D mouse drivers should not be touching geometry… as far as I know this was due to renderers.

i turned off the autosave for few days. Didn’t the problem since then.
