How to get correct translation and rotation of part in step file

[leoghizoni]

I'm trying to implement a function to retrieve the translation and rotation of the parts in an assembly step file. I found the function read_step_file_with_names_colors(filename) inside DataExchange.py with the locations commented, and implemented in my code. When I get the numbers, they match perfectly with the parameters shown in a CAD program e.g. FreeCAD.
However, the positions are exactly the same for different parts, both in FreeCAD data and in my output, which I know not to be true, as they are shown in FreeCAD in different locations. I've read something in the internet about the vertices of a part actually being in the correct positions, but I have no idea how to implement that.
Is there a way to actually getting the correct position of a part in the "world" of the assembly?
Thanks in advance.
