Design an architectural course poster, with the theme centered around the deduction process of architectural thinking and the three-dimensional cultivation of space. The centerpiece should be an abstract, three-dimensional architectural model that displays multi-level and interlocking structures, using bright colors like blue, red, and yellow to attract attention. Surrounding the model, there should be dynamic lines and shapes symbolizing the flow of thought and the stimulation of creativity. The background should transition from soft to bright colors, emphasizing the theme of the poster. --v 6.0
