Abstract
Modern engineering practice demands that students master digital design tools and spatial modeling beyond static drafting. This work presents an integrated, simulation-based methodology for Engineering Graphics education that tightly couples classical projection topics with CAD modeling, automation, and immersive technologies. In our approach, students engage in an iterative CAD-centered cycle (modeling, analysis, redesign, verification, evaluation) supported by a digital learning environment with 3D content, real-time feedback, and modern interfaces. Key features include the use of AutoLISP scripting in AutoCAD to automate parametric drawing tasks, and the incorporation of virtual (VR) and augmented reality (AR) modules for interactive visualization. A pilot implementation with 60 undergraduates indicates that this methodology significantly boosts student engagement, spatial reasoning, and design accuracy compared to traditional methods. Students in the enhanced course finished design tasks
