You can model wall internals in 3D, and Section will show you the contours of each element's cross section.
However, to automatically display them with appropriate hatches is not possible in Sketchup.
It's a feature found in BIM software, like Autodesk Revit. Sketchup acts more like 2D CAD application here.
That said, you can send the sectioned scene of a model to Layout, and add hatches manually by drawing shapes and choosing pattern for them from Layout Scrapbooks.
