In 3D view, AVF surfaces are not cut by the section box, so in a top view, the top floor results are always shown. You can turn on and off individual AVF photometric surfaces by level, so you can explore each level in detail in a 3d view, create overhead views for each level, etc. You can hide the AVF levels in 3d view in two different ways.
