Save screws up geometry.
-
If you are generating tiny faces in your model try running a validity check before saving. Window>Model Info>Statistics>Fix Problems. That'll give you an opportunity to fix them before you save.

Thanks for the reply, I do tend to enlarge anything before I make or adjust fiddly aspects of a model to save time really, a little bit of affirmative action does help, thing is it happens at times 100 of model size and nothing in a model that large is going to be small exactly. I think I am just getting a bit jaded with the whole sketchup falling over thing, OK the first hundred times but after that a bit more than should be the case.
I have been told that the biggest issue with sketchup is not the program itself but the interaction with rubies/plugins. If this is the case, the time for all plugins etc to be made in house is here. Either that or bring in a method of stress testing EVERY plugin for suitability BEFORE it is released.

Out of curiosity, Mike, what kinds of things are you drawing? I wind up making and using a lot of small, fairly detailed and complex components for many of the projects I have and I don't have problems with SketchUp saving those things.
-
This is a known glitch. It happens if you save while something is selected. Get in the habit of unselecting items before you save, and while not working on the model (it can happen with autosave as well).

@Sonder: Is this officially published anywhere?
-
Sorry, I was referring only to the smoothing aspect. This has been discussed here multiple times. The disappearing geometry is new to me. I have never seen that. Check that you haven't accidently assigned the geometry to a hidden layer.
-
Well, what you say is good practice, anyway. I was thinking that there may be an outside link that I may have missed. Actually, what I may have missed could fill the Library of Congress
-
The latest model was an i-pod docking station, a simple thing with little in the way of complexity.
-
Sonder, no layers other than base so no layers to assign anything to.
-
Got some steps to recreate a model that behaves like this?
I've also never experienced this.
-
I could see a scenario where it happens.
If you have set your model to automatically fix problems and not let you know, then SU will fix all non planar faces and broken face loops and stuff. Sometimes in the process of fixing things, geometry gets deleted. If you have it set to not warn you that it is fixing your model, then it may appear that geometry is being randomly deleted.
That might be a possibility.

Yes this is possible. Happened to me many years ago. It is due to inaccurate modeling by the user. For a long time on a particular house mode, I couldn't figure out why this was happening, until I found the error myself.
In my case it was a single roof plane that was not aligning correctly, so when the fix dialogue box would come up, I would click "yes" and the roof plane would disappear. Once I re set the roof, it never happened again. So I have experienced this, but only once in 2006.

I've had a few models that this happens on regularly. One was made by another guy and I inherited it. That model would regularly have issues that ended up in deleted geometry.
A few others I made myself from CAD imports. Its not too common, but also not completely uncommon. And maybe certain modeling habits lead to more problematic models.
So its not really probable, but it is a theory of what could be happening
