Body Fixed Co-Ordinate System.

How does Cura decide where the body fixed co-Ordinate system(the one which appears on the body when you are in the move command) is placed?

It appears to symmetric to the part in the X-axis but not in the Y and Z-axis...

The widgets are drawn centered to the boundigbox of the model or group. For the coordinates shown in the move tool, the z aligns with the bottom of the bounding box, so it is easier to place objects on the build plate.
