Green possessed a unique ability to deconstruct complex 3D concepts into manageable 2D exercises. His approach combined rigorous British Standards (BS) conventions with a step-by-step methodology that catered to beginners without insulting advanced learners. When educators refer to a , they are looking for this specific blend of rigor and accessibility.
