AR-OrthoDraw: Hybrid Augmented Reality Spatial Visualization Training Kit for Orthographic and Isometric Drafting Mastery

About the Project

AR-OrthoDraw is an innovative hybrid training kit designed to overcome cognitive spatial visualization barriers in learning orthographic and isometric technical drafting. Traditional 2D paper-based drafting often induces high cognitive load for art and design students who struggle to mentally translate three-dimensional geometry into standard orthographic projections. AR-OrthoDraw resolves this pedagogical gap by seamlessly integrating low-cost printed marker workbooks with an intuitive mobile Augmented Reality (AR) application. By scanning the physical exercise sheets with a standard smartphone or tablet, learners interact directly with dynamic 3D models mapped over their drawing space. Key innovations include an automated "glass-box" unfolding animation demonstrating first-angle and third-angle projections, dynamic cross-sectional slicing along X, Y, and Z axes, and an instant visual overlay to verify student pencil drafts against actual geometries. Preliminary testing indicates a substantial reduction in conceptual drafting errors and accelerated spatial mastery without requiring high-cost VR headsets or industrial CAD licenses. Lightweight, offline-ready, and scalable, AR-OrthoDraw presents highly viable, market-ready STEAM learning solutions for TVET centers, secondary schools, and higher education.
