The usual section view options do a great job cutting away portions of parts and assemblies. However they do lack functionality when it comes to cutting away just some of the geometry. For instance we could not achieve the cut away view with a standard section view.
To create this type of section view one must use Extrude Cut. First create a separate configuration and call it whatever you want. Then create a rectangle on a plane that intersects or is off of the geometry. Use Extrude Cut with Feature Scope.
Only select the items that you want to cut away. This will produce the image in the first picture.
