The section plane and cast shadows, 2017

I don’t think SketchUp native section planes or plugins have such feature.
However Vray plugin has a feature called Mesh Clipper which does what you need.

Here is an example where user defined mesh used as ‘clipper’ and house geometry affects the scene/lights as if it’s there.
