TLDR: In this article, the utility model discloses a how much teaching aids that mechanical drawing used, and the characteristics of the transform rapidly, the knowledge point show is efficient, the demonstration feels strong etc.

Abstract: (B, ) the utility model discloses a how much teaching aids that mechanical drawing used. It includes mutual perpendicular to each other H perspective plane (1), V perspective plane (2) and W perspective plane (3), is equipped with lamp pearl (4) of arranging with the dot matrix form on H perspective plane (1), V perspective plane (2) and W perspective plane (3), being provided with support (5) in the top on H perspective plane (1), being equipped with projection thing (7) that comprise lamp strip (6) on support (5), lamp strip (6) and lamp pearl (4) warp way is connected with controller (8). The utility model has the characteristics of the transform rapidly, the knowledge point show is efficient, the demonstration feels strong etc, and the utility model discloses can increase student's enthusiasm and interest in learning.
