This article discusses the possibility of compound courses in the teaching of basic design. The traditional three-dimensional design course and the spatial understanding course are effectively integrated, and the "Three-Dimensional Design and Spatial Understanding" course is innovatively set up in the teaching of the basic ministry. This course aims at adapting to the general trend that the basic design teaching of the College of Fine Arts emphasized compound ability and broadened professional vision, focusing on comprehensive training of practical ability and thinking ability, communicating two-dimensional and three-dimensional thinking. Breaking through the barriers of real space and virtual space, and integrating conceptual recognition with practical training in an all-round way.
