Research on Intelligent Modeling Analysis and Recognition System in Architectural CAD Engineering Drawing

In mechanical design, this paper uses CAD interface for 3D modeling to generate 3D solids. This paper clarifies the intelligent standard view generation technology in 3D CAD software and its intelligent technologies such as axonometric drawing, internal structure, auxiliary view, intelligent annotation, parametric design and assembly design, showing its powerful application function. According to the principle of shape design in 3D conception, this paper discusses the teaching mode of combining composition theory with 3D CAD application, and using 3D CAD system to cultivate students' abstract thinking, image thinking and innovative thinking.
