Hi, everyone.
The ActiveObject is NoneType after the boolean operations on the model.
Why? How to get the active object in the python console? Thank you for your help.

Thanks! To be honest, I don't know. In the python console, FreeCAD defines the "ActiveObject" as "the active object in the document".

Ignore what FreeCAD says. What is your need?
