I am designing a model of a V12 engine and gearbox combo for a model car. I have created most of the engine internals without a problem but I am constructing a crankcase around said internals and SketchUp won’t consider the crankcase component as a solid. Because I am running through a free school account, and because of my platform, I only have limited native tools and no solid inspector. I have read about other people’s problems before on these forums in order to solve my own problems but at this point, I am out of ideas.
Disclaimer: This is only half the crankcase I was planning on using the flip along ____ axis, function to create the other half. Also, the actual model itself does not include any of the internals portrayed in the pictures and is just the raw component.
I have been checking the entity info tab religiously throughout the creation of the component so I have a relatively good idea of when the problem would have occurred. After creating the part that houses the cylinders (most visible in picture one) the component was solid. Then I added the clutch housing (circular hub on the front of the model visible in picture three) intersected it with the part that houses the cylinders and that was solid too. Then I added the flat plate on the backside of the model (visible in pictures one and two) and intersected it with the first two parts and these three formed a solid component. The problem occurred most likely in the next 2 steps because after these two it would no longer register as a solid. In step four I added the interior of the crankcase (Most visible in picture two) and intersected it with the rest of the model. I was not able to check step four in the entity info tab because it only formed one face, however, I highly doubt that the problem occurred here because the intersect faces tool did its job flawlessly. In step five, where I believe the problem occurred, I added the outer ribbing (visible in picture one) this also should have created the faces that made the model solid again however I had some trouble with the interest faces function where the faces created in this step meet step one. At the end of steps four and five, the model no longer registered as a solid even though I could have sworn it should be. Even though it wasn’t solid I decided to do some final touches (like the hole in the bottom of the crankcase) before I came and asked you guys.

I know this is a mouth full and a half, but I would appreciate all of the help I can get to make this a solid component for 3D printing. Also, it would be great to know: Other than using the entity info function, what can I do with native tools and no solid inspector to try and prevent or fix future non-solid components and turn them into a solid?
Thank you in advance.
