Improve the teaching content and teaching method of perspective drawing: directly from the layout

take the introduction of drawing methods of various drawing lines as the principal line to arrange the content

select the drawing with moderate difficulty and highly targeted as the example drawing

introduce the drawing method in the drawing

briefly prove the drawing principle of each drawing method

summarize the drawing method of each type of drawing line immediately after speaking

so that the method can solve one Class problem

not a problem. It overcomes the disadvantages of the existing explanation methods: either focusing on the perspective law of points

lines and surfaces[1]

with strict logic

but hard to understand

There is a disconnection with the guidance of drawing; or directly introducing the drawing method [2]

without proof

without induction and summary

which makes it difficult for students to grasp the applicable scope and plotting essentials.
