gc.get_objects()

[Matteo Boscolo]

from my gc.get_object()
I extract the sub system of the object that I would like to delete:

this is the object:
Class name 
win32com.gen_py.F4503A16-F637-11D2-BD55-00500400405Bx0x1x0.ITDProperty.ITDProperty
that is traked and the reference are:

RefCount 5
<type 'tuple'> >>>>  (<class win32com.client.DispatchBaseClass at

how can I understand how to clean up this situation or were are the 
references that I need to delete ?

 From the cad non python script I call an in process python com object, 
and before coming back to the cad application I need to clean up all com 
reference, because if I do not do that I corrupt the cad application .

so I urgently need to clean up all reference before coming back to the 
cad application.

any idea?

regards,
Matteo
