Against the backdrop of urban-rural built-stock regeneration and digital transformation, traditional Principles of Urban Planning teaching suffers from theory-practice separation, inadequate engineering training, lagging digital tools and simplistic evaluation. Taking the intelligent construction competition and the wooden house renovation project at Fujian Agriculture and Forestry University as a case, this paper integrates 3D scanning, point cloud modeling, BIM reverse modeling, performance simulation and digital twin into teaching, creating a workflow consisting of project introduction, data acquisition, model construction, problem diagnosis, scheme design, competition defense. It transforms spatial cognition, adaptive renewal, low-carbon decision-making and planning implementation into practical tasks, forming a competition-driven, project-centered, intelligence-assisted, performance-oriented teaching mode. Practice shows it shifts students from rote memorization to problem analysis and from single-scale to multi-scale thinking, improving their digital- modeling, teamwork, decision-making and presentation skills. This approach provides insights for interdisciplinary talent training for urban-rural planning.
