Find the outer edgeloops of a wall completely split in two

[m.de.vriesTH5VM]

I have a wall that is completely bisected by a window (i.e. the window is taller than the wall itself)

Normally the lazy way to find the outer edge loop of a wall is to select the first from the EdgeLoops property of the geometry, and treat subsequent loops as openings.

This clearly will not work for the wall that I am working with, as it must have two outer edge loops. (and if I were to insert the same window another time in the same wall there would have to be three outer edge loops).

My question is now if there is a way to distinguish edge loops for the outer shapes from the ones for openings.

Historically cad applications did this by defining the outer edge clockwise and openings counterclockwise. I could not tell if this applies to Revit as well, since the geometry definition frequently has artifacts of the editing process (like additional points splitting an edge or even missing edges that can be implied from the geometry).

Thanks in advance for any information that I can use to solve this little problem

Thank you for the answers. The third topic was the specific answer to my question as it turned out.
