At 6:40 you perform a rotation in Edit Mode, yet the Local orientation does not reflect the change. I'm having a hard time understanding why the local orientation did not change to reflect the transformation. It seemed like initially, we established that transformations in Edit mode affect local orientation, and transformations in Object mode affect global orientation. Yet the rotation in Edit Mode did not reflect in local orientation...?
  • Is it that translations have to be done in edit mode, and rotations have to be done in object mode, for the local orientation to behave as specified in the video?
  • Now I am performing transformations (both translation and rotation) in edit mode, but in object mode, the global and local orientations are the same... I am very confused.

    Global vs. Local space can take a bit of time to wrap your head around. No worries. Think of this way: in global space all object transforms happen along the same axis, regardless of the existing object orientation. Local space, on the other hand, works based on the current orientation of that object. A quick way to test this: in object mode rotate the default cube 45 degrees along any axis, then switch the manipulator axis to Local Space. Notice how the manipulator now follows the object orientation, while in Global Space it does not? When modifying the mesh in Edit Mode, no changes are made to the object orientation; rather you can choose to transform the geometry along the local orientation of the object you're modifying.
