This paper aims to briefly introduce the digital architectural design teaching system gradually built in School of Architecture, SCUT, which features in "vertical and horizontal integration"; analyze the specific patterns and implementation experiences by which this system connects and adapts rationally to the original design teaching system through "vertical" advanced arterial digital design course and "horizontal" integrated digital design special training, in order to provide useful reference for related teaching research and innovation practice.
