create cross sections from objects that are arranged in a cross section geometrically, but still not formally attributed to a cross section (e.g. objects imported from other software).
delete a cross section and keep its entities, transforming them to generic 3D entities (e.g. XsPolyline -> Polyline).
delete a cross sections and all its child objects.
This is a more general issue than #35.
