I just got done extruding this mesh and It hasn’t update the scale in the brush settings, And was wondering if there was a way to update the scaling to show me the proper measurements?
If you want the scale in the details panel to keep pace, that’s where you have to update it 
( don’t do it using the widget )
So don’t extrude it using the geometry editing tab?
Introduce a cube brush, for instance. If you scale it using the widget, the brush size in the details tab wont change. If you want the numbers in the details to change, you have to scale it from the details tab.
I don’t know what the ‘deep’ meaning of this is…
