Teaching practice of enhancing three-dimensional modeling ability through Slicer deconstruction training

This project revises the required first-year “Three-Dimensional Design” course. In previous advanced design courses, students often struggled with 3D software or relied too heavily on 2D visual presentation, resulting in limited understanding of three-dimensional form, curved surfaces, orthographic views, and proportional relationships. To strengthen beginners’ observation, spatial imagination, and deconstruction abilities, this project introduces Slicer-based deconstruction training. By transforming closed contour lines into sections and assembling them into new forms, students learn how 2D structures can be converted into 3D curved surfaces. The training combines physical model-making with computer modeling to enhance students’ spatial design abilities.
