Projects in this category are original works digitally created and modeled in three dimensions using specialized software. Entries may represent objects, environments, characters, prototypes, or other creative or functional designs.

Models are not required to be physically printed or fabricated; however, they must be demonstrated digitally in the software used to create them. Students should be prepared to explain their design process, the tools and techniques they used, and the intended purpose of their model (such as visualization, simulation, product design, or artistic expression).

Examples of eligible software include (but are not limited to):

• Beginner-friendly: Tinkercad, GollyGee Blocks (iOS)

• Artistic/animation: Blender, ZBrush, Maya, LightWave

• Engineering/architecture: AutoCAD, SketchUp, Fusion 360, SolidWorks

• Emerging tools: Unity (3D modeling integration), Roblox Studio, other educational 3D platforms
