I would like to export flat BOM recursively from the top model and get all the parts and sub parts using API,

is it possible?
I don't wish to open each sub model in order to get it and then to combine it.

I know already to take from the drawing the bom feature, but in this case it may be better to go to the model file.

Thanks!

P.S in Autodesk Inventor there is such option using the API
