SOLVED Filling hollow spaces?

Hello there.

I've found something on Thingiverse and wanted to print it. I had to split the body into four parts and now have encountered a little problem in Cura while I examined the pieces.

The bottom of the case pieces is, as soon as I look at the body in layer view, grayed out and won't print either.

The shape shows the bottom and looks like this:

When I switch to layer view, it looks like this:

How can I fill out the spaces with Cura?

I'm using version 3.0.4 on Windows.

The problem is with the cad model unfortunately. It's not manifold I strongly suspect. I recommend passing it through the free netfabb repair web service:

I think microsoft has an STL repair service as well.

Hello gr5.

Thank you for your answer, as well as solution. I tried Netfabb, uploaded my STL and got it back with the bottom layers now appearing in Cura as well.

Thank you for your solution.
