IFC entities extracted twice

As Larz said, you should be posting in code tags. You're far less likely to get a reply if people have to go off-site. Also, I haven't looked at the links but the shorter the code the better - if you can reproduce your problem in 5-10 runnable lines of code rather than hundreds, you'll be substantially more likely to get a reply (and faster at that).

Thank you for your reply. I will definitely use BBCodes while posting any question.

from __future__ import print_function

f = ifc.open("C:\Users\GURBHEJ SINGH\Desktop\Beam_Material.ifc")
f2 = ifc.open("test22.ifc")


directions = f.by_type("ifcdirection")
for direction in directions:
   f2.add(direction)

beams = f.by_type("IFCBEAM")
for beam in beams:
   f2.add(beam)

f2.write("test22.ifc")

Error:
Traceback (most recent call last):
  File "C:\Users\GURBHEJ SINGH\Downloads\python\Abcdef.py", line 3, in <module>
    f = ifc.open("C:\Users\GURBHEJ SINGH\Desktop\Beam_Material.ifc")
NameError: name 'ifc' is not defined

Please help me to solve the issue.
Thank you.
