“The architectural charting and drawing recognition” is the theory and method that studies drawing and reading of the architectural engineering plat, and also is the main technological curriculum that raises senior engineering applied talents in product line for related majors.
The architectural engineering plat is one kind of the engineering plat, which is used to express the shape, size, material, structure, construction mode of the building as well as the specification and so on[1]. It is not only an important tool to express design intentions, exchange technology thoughts, but also an important technical document to instruct technical work such as production, construction, management and so on.

Three-plane projection drawing
Three-plane projection drawing is the main pattern in the project, which can accurately reflect the shape and size of object and is convenient to chat[2]. In the ordinary circumstances, three-plane projection drawing is composed of the horizontal projection drawing, the frontal projection drawing and the pro drawing. In the analysis process of three-plane projection drawing, we are required to follow the projection relation of “equality in height, width and length”, which is the foundation of drawing and reading.
The primary coverage of this curriculum includes: elementary knowledge and skill of charting, projection charting and the architectural engineering plat and so on.

First, Projection charting The concept of projection
The projection phenomenon refers to that if a object is irradiated under the sunlight or lamplight, it will leave a shadow on the ground or on the wall. By scientifically and abstractedly summarizing the relationship between object and shadow in the long-term production practice, people sum up the method of projection. The projection is widely used to express the object in the engineering circle, so as to realize the interconvertion between three-dimensional objects and two-dimensional objects.
