Modify your path and name of file, save and load the macro and run.
fichier = "C:\yourPath\cloud.asc" # path and name of file.txt
If you want a close wire modify this line (closed=False):
Draft.makeWire(wire,closed=False,face=False,support=None) # create the wire open
and replace with (closed=True):
Draft.makeWire(wire,closed=True,face=False,support=None) # create the wire closed
same for the face, False or True (face=True).
