title: Bounding Box intersection
body: <p>To find elements that are intersecting a geometry I am using the example post by Jeremy in his blog <a href="http://thebuildingcoder.typepad.com/blog/2010/12/find-intersecting-elements.html" rel="nofollow noreferrer">http://thebuildingcoder.typepad.com/blog/2010/12/find-intersecting-elements.html</a>. But the bounding box is always paralell to the axis X, Y and Z and this may cause a problem, like return elements that are not really clashing, because sometimes the bounding box it's not always coincident with the geometry because the family instance is rotated. Besides that, there is the problem that the bounding box will consider the geometry of the symbol and not the instance, and will consider the flipped geometry too, it means that the bounding box is bigger than I am looking for. Is there a way to get the real geometry that are in the currently view ? How can I solve this problem ?</p>
