These videos intend to show a powerful way to execute basic Wings3D commands (move, rotate, scale). Usually, to work with these commands AND constructing the vector (that indicates axis and/or reference point), you have to call them by clicking on it with RMB.
Read Info Line while pointing to any of those commands, and before execute. Read and construct your vector (axis+ref point).
So Wings3D user has: . Move (along an axis) . Rotate (along an axis, setting or not a ref point) . Scale (idem)
