Oh that looks good. I think you did a good job in sketchup there. Congratulations. I still recommend you bail on sketchup if you have less than 100 hours experience with it. If you don't please please read that guide above.
Also ALWAYS look at the part in layer view and run the layer slider up and down - pay particular attention to the bottom layer but also pay attention to possible overhang situations.

sketchup is a bit dangerous with 3d prints - it's better for virtual models - not physical models - so if you haven't spend a hundred hours learning sketchup I strongly advise you to stop right now and use something else. Here's a guide to pick CAD:

However if you really want to stick with sketchup then you need to completely read this guide and understand it. Particularly about the reversing walls part:

Now to answer your question - I think I need a screenshot of your stl in cura in normal view, xray view, and layer view to understand what you are talking about. By default I think cura does a 20% to 30% infill which should fill in your part with a criss-cross kind of pattern in the "solid" areas. If you set infill to 100% you should get solid parts. But that's a huge waste of money and time for no inmprovment in strength. The gradient thing you speak of is called "gradual infill" and it's a great feature - I use it all the time.
But I think there is something lost in the translation - I strongly suspect your sketchup model has some serious issues that are confusing cura thus causing these "hollow" things you speak of.

Hey!
Ok the criss cross pattern should be good enough what I'm trying to get done. It's my first run on something of my own design and I guess I should've waited until it was done printing before I posted my question, but I think you've calmed my worries haha.
Screen shots attached just for verification.
