Draw A Vertical Section Through A Stairs 

Glad you like it ....i agree that we need more of this type of animated content in apprenticeship which makes learning more accessible to the apprentice whose prominent stlye of learning is Visual.... this helps form part of a "Universal Design for Learning" strategy. Its a nice "Flipped Learning" option to have if you want the apprentice to view the animation on their smart TV at home the day before the instructor delivers the lesson on the class room/workshop. This option definitely speeds up the transfer of knowledge and skill while make the learning process more blended .....and more enjoyable.

Thank you! Cheers!
