A quick way to create a 3D view for each level in your project is to use the Orient to View option in the View Cube right click menu. This can be done by opening a 3D view and hovering over the House icon on the View Cube, and right clicking to open the right-click menu.
In the right-click menu, select Orient to a View, Floor Plans, and then select the desired floor plan to orient to.
The view will automatically crop the view using the Section Box to match the View Range for the view that was selected. It will also rotate the view to view it from the Top direction. You can orbit the view any direction you want but the view is now cropped to match the floor plan's View Range.
