Analysis of ATC-type Stair Structure by Axonometric Projection Drawing Demo

In the teaching of architectural engineering drawing, beginners usually need a sense of space and help to understand the graphic expression content and building entities. The typical way to solve this problem is to use software to build a three-dimensional model for demonstration. However, this method has some disadvantages, such as difficulty operating a single demonstration, lack of change, and test demonstrating according to the cognitive process. In this paper, axial projection drawing is used for demonstration in the teaching of architectural engineering drawing recognition. Take ATC-type stairs as an example; step-by-step analysis is carried out with the help of MSPaint drawing tools. As a result, the drawing rules of progressive cognition, the study of factor changes can be carried out from easy to complex in line with the cognitive habits of the human brain-friendly to beginners and has achieved good results in actual teaching.
