#    Draft.makePoint(float(X),float(Y),float(Z))            # create points (uncomment for use)
    print(X," ",Y," ",Z)
    wire.append(FreeCAD.Vector(float(X),float(Y),float(Z))) # append the coordinates

file.close()
Draft.makeWire(wire,closed=False,face=False,support=None)   # create the wire open
#Draft.makeWire(wire,closed=True,face=False,support=None)   # create the wire closed (uncomment for use)

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).
