How can get all the point on the edge of the floor?

[Anonymous]

As my title, I want to count all point on the edge of the floor but I don't have any ideal for do it. Does anyone has a solution?

My ideal something like this:

int i = 0;

FilteredElementCollector docCollector1 = new FilteredElementCollector(doc).OfClass(typeof(Point));

foreach(Point point in docCollector1)

{

  i++;

}

TaskDialog.Show("Revit","Have total {0} point on the edge of the floor ", i);

You can add a geometric location filter, e.g., using a 

BoundingBoxIntersectsFilter

Here are some examples:
