Geometry API
§HostObjectUtils - locate the faces of a given roof, floor or wall (host objects)

§ExtrusionAnalyzer - Allow fitting a geometry into the shape of an extrusion

§Geometry Filters - find elements that intersect the solid geometry of element
§ElementIntersectsElementFilter
§ElementIntersectsSolidFilter

| Geometry API now provides shortcuts to locate the face of a given roof, floor or wall – basically host objects, using HostObjectUtils.
| We can also fit a given geometry into the shape of an extrusion using the ExtrusionAnalyzer class.
| Revit 2012 API has new geometry filters which help find elements whose actual 3D geometry intersects the 3D geometry of target object. With ElementIntersectsElementFilter, the target object is another element.
| With ElementIntersectsSolidFilter, the target object is any solid, including one created from scratch using GeometryCreationUtilities. Both these filters are slow filters.
