3d – How to find center point from an fbx file with multiple meshes?

N00b around here – I’ve been pulling my hairs when trying to understand how to get the center point (or offset pivot) of an fbx with multiple meshes but I’m out of luck, so resorting to StackOverflow!

I have the following fbx file which I’m trying to get its center point. I was given this fbx as an example by a 3D artist and by opening the file in Blender (see image below) I can see that the center point of the pole is at the bottom. However, despite of writing a several scripts extracting the info contained info (example here), I haven’t been able to find where this center pivot is located.
