from pycatia import catia
from pycatia.product_structure_interfaces.product import Product
from pycatia.product_structure_interfaces.product_document import ProductDocument

if __name__ == "__main__":


    caa = catia()
    documents: ProductDocument = caa.active_document
    product_document = ProductDocument(documents.com_object)
    root_product = Product(product_document.product.com_object)
    
    inertia = root_product.get_technological_object("Inertia")
    
    print(inertia.GetInertiaMatrix())

Hi
I ve got a tree which contains different CATProduct and i wish to get COG matrix from the first one.

• Root node

• CATProduct1
  -CatProduct2
  -CatProduct n
  -CatPart1

  File "C:\Users\Desktop\MacroApp\macro\macro_thomas.py", line 31, in
  print(inertia.GetInertiaMatrix())
  ^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "", line 2, in GetInertiaMatrix
  File "C:\Users\AppData\Roaming\Python\Python312\site-packages\win32com\client\dynamic.py", line 356, in ApplyTypes
  result = self.oleobj.InvokeTypes(
  ^^^^^^^^^^^^^^^^^^^^^^^^^^
  pywintypes.com_error: (-2147352567, 'Une exception s’est produite.', (0, 'CATIAInertia', 'La méthode GetInertiaMatrix a échoué', None, 0, -2147467259), None)

I have this error ... with catia i can click on Mesure Inertia button and have the result.
Best regards

print(inertia.GetInertiaMatrix())

This looks like user error.

pycatia uses python naming conventions (https://peps.python.org/pep-0008/), So, you would not see ClassName.ClassMethod() type call ups.

Take a look at this example: https://github.com/evereux/pycatia/blob/master/examples/example__inertia__001.py
