Hi,
I am new in SketchUp and trying deperatly to make my object solid. Tried the solidinspector and solidinspector2 plugins but I still don’t get what’s wrong with my object and how to correct it without throwing away days of work. Is there any other automatic tool to solidify my object ?

Thanks.

There’s some pretty complex geometry going on there in the curved slide. That’s probably where you have some rogue elements that are failing to “close” the solid. Might take some finding though.
Yes,the thing is that when I zoom, I don’t see where it comes from.
I have not had a chance to dive in too deep, but it looks like you have a LOT of internal faces… Remember, to have a manifold shape, each edge should connect with only one other edge. The whole model should be an exterior shell of your model.
Am I right that you imported this from an .stl file created by some other app? The excessive triangulation and bizarre coordinates of points in the model suggest so. I spent the time I have available today and there were still 4 remaining internal surfaces that I couldn’t track down and correct. I suspect they result from tiny edges that are present even at the large scale you have your model. Fixing this model completely is going to take a lot of effort!
I would recommend that you create section planes to examine the innards of the model. Many of the flaws can be seen that way. For example, see all the internal faces in this screen shot:
There are also some internal faces that are very hard to see because they are extremely narrow. You can try a repeated cycle of looking at Solid Inspector 2, fixing what you can, and then looking at SI2 again to see what remains (or what you have made worse).
There are also a few small holes underneath the slide on each side near the top. Tiny triangular gaps.
There are a lot of reversed faces. I suggest you change the back side color of faces in the style to something outrageous (I use an annoying green) so that reversed faces are easier to see. Consistent inside vs outside face color can make it easier to spot holes: they show as back face color because you are actually looking through the hole at the inside of some other face.
A tip on the wonderful Solid Inspector2 extension: you can select a category (such as Surface Borders) in its window and then repeatedly press TAB. This tells the extension to surround the next instance of the chosen problem with a red circle. You can then zoom into that area for manual inspection and correction.
Thanks for the time spent. I created this with Sketchup 2015. One of the problem encountered was that I put the original sizre of the object which was quite small and gave some strange results. Then I multiplied the size by 1000 which solved some issues, bue created others. Can you upload what you obtained by fixing what you could ? I will then continue manually.
Thanks for your help.

What really surprises me is that there is no powerful cleanup tool to remove all the inside useless lines surfaces etc …
50$ to the guy who makes this model solid !
Soild-Inspector has a go, but it isn’t perfect.
My SolidSolver [available via sketchucation] has similar fixing functions - including some extra ones.
But again it’s not perfect.
You as the modeler can contrive all kinds of convoluted 3d geometry that renders your form non-solid.
As a programmer it’s all but impossible to fix some of these - decisions must be taken as to what needs to be kept and what is superfluous.
As a modeler you are best placed to fix these more complex things - use temporary section cuts to see inside your 3d geometry, and then tools like Solid-Inspector to highlight your mistakes…
…and keep checking whether SketchUp declares your object to be Solid as you go about creating it. Don’t wait until you’ve put 20 hours into some complex structure to decide it’s finally time to see if it’s a Solid.
I got some more time to look at this. Here it is, solid:
