Following Script from a guy at Cgsociety did the work for me.

import c4d
from c4d import documents as docs

class ObjIter:

def __init__(self, obj):
self.obj = obj
self.currObj = obj
self.objStack = []

def __iter__(self):
return self

def __next__(self):

if not self.currObj:
raise StopIteration

obj = self.currObj

if self.currObj.GetDown():
self.objStack.append(self.currObj.GetNext())
self.currObj = self.currObj.GetDown()
else:
self.currObj = self.currObj.GetNext()
while not self.currObj and len(self.objStack) > 0:
self.currObj = self.objStack.pop()

return obj

def main():
doc = docs.GetActiveDocument()
obj = doc.GetFirstObject()
scene = ObjIter(obj)

for obj in scene:
if isinstance(obj, c4d.PolygonObject) and obj.GetPointCount() == 0 and not obj.GetDown():
obj.Remove()
c4d.EventAdd()

if __name__ == ‘__main__’:
main()
