Thanks for clearing that up for me. I was trying to close down the holes and fix it, only to run into that same problem again. Which basically lead me to redrawing those parts again, but it's fixed now. Thanks!

So I'm working on a project at the moment, and well...this never happened to me before. I'm using SketchUp 8.0.16845 and now when I'm trying to save my progress it simply deletes a lot of the geometry, so lots of lines and surfaces simply disappear.

Not sure what's causing this though. The file isn't that big (around 12mb), I've worked with bigger, more complex stuff, so I doubt it's that.

Anybody have any similar experiences?

Thanks a lot for the help guys! I've been playing with the Solid Inspector, which works like a charm! It works that great that I no longer need stuff like Netfabb to fix the model.

SketchUp does already have boolean tools! It's called Solid Tools. You can always do it manually do, by intersecting and deleting geometry.

Tak2hata also wrote a bool plugin, as have others.

That means you already need to have solid objects. I was kinda hoping for a feature that would easily and automatically make my model solid, meaning I can just easily draw stuff without having to worry about geometries and such.

Like I said...I'm feeling lazy.

if you don't make mistakes you will never learn we all do it! won't take you long to model something like that again; lots of repeating elements where if you get one right, they will all be right. There is also a solid inspector plugin to see where the holes are.

I've got the solid inspector plugin, so I will give it a shot with that.

I guess I've grown a bit lazy, kinda hoped a new version of SketchUp could automatically make a selection solid if it doesn't have too big holes. But yeah, that's just super wishfull thinking I guess.

Sorry, I'm just a bit bummed out. Spent a lot of time trying to do this and then realized that I basically did it all wrong with the geometry. I thought I created a solid model, which apparently I didn't.

Yeah, I kinda figured that. Means I probably have to start all over again.

Man, I should learn Blender...

Sure.

I've been working on a spaceship model for 3d printing. And I've been unable to make some shapes by just push/pull, so I used the line (pencil thingie) to put these shapes together (especially in the front).

The model in the attachment is still very much a work in progress, so don't judge on that yet. But I did however wanted to see how printable it would be (wall thickness and all that). So I converted it to an .stl file and then used Netfabb's cloud service to fix the watertightness, but what I get back is a model with lots of parts missing and giant chunks taken out of it.

Thing is that apparently the model isn't watertight since I didn't do all my shapes using push/pull, which is rather frustrating. Would be nice if all enclosed shapes you make, be it through push/pull or just put together with lines, would automatically be watertight.

Once thing I'd love to see in SketchUp is that a drawn object (not just through pull/push) is automatically watertight. I notice that when I try to draw some 'weirder' shapes that don't involve pull/push, so just me putting them together with the pencil thingie, that the object isn't considered fully enclosed. It's very frustrating when having to do weirder and more organic shapes in SketchUp using push/pull, so it would be great if a shape could be fully enclosed when put together with the pencil thingie as well.
