Sorting Elements and Views by level to name in a logical order

# The inputs to this node will be stored as a list in the IN variables.
wallList = IN[0] # Wall Elements
geoList = IN[1] # Wall Geometry (geo)
sortWall = [] # Final sorted list
sortGeo = [] # Final sorted centerpoints
orig = Point.ByCoordinates(0,0,0) # Point used as origin

for _subG,_subW in zip( geoList, wallList ):
    _temp = [] # Sorted wall sublist
    _geo = [] # Sorted geo sublist
    t0 = orig # Base geo for comparison
    while len( _subG ) > 0:
        t5 = [] # List of distances
        for i in _subG:
            t5.append( Geometry.DistanceTo( t0, i ) )
        t6 = min( t5 )
        t7 = t5.index( t6 )
        _temp.append( _subW.pop( t7 ) )
        t0 = _subG.pop( t7 )
        _geo.append( t0 )
    sortWall.append( _temp )
    sortGeo.append( _geo ) # Add 'sortGeo' to output for sorted geo

OUT = sortWall

So this uses the point (‘orig’ in the script, can change to whatever) as the first comparison. Also if I have time I will clean up the script later and replace the terrible variable names to make it easier to follow. I think using the wall line instead of center point works better but let me know how it works.

Edit: Cleaned up the python a little bit.

Honestly actually amazing. Thank you so much. I changed the coordinates to -99999,-99999 encase the 0,0 is ever in the middle of elements. Will always start from bottom left always now. So great, thank you
