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:

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

The __del__ method does not delete an object. Remember, objects are only
deleted when there are no references to it. Otherwise you could have some
code that tries to use a deleted object, and you would get a system crash
or BSOD.
There is a conceptually viable alternative: destroy an object
immediately and force all references to it to become some sentinel
value (eg None). Python currently doesn't have this, but it would be
rather convenient at times. Could be part of a construct like 'with'
to say "make this, use it, and then dispose of it".
