How to model packaging 3D models for industrial designers?

Industrial designers model packaging 3D models by first gathering requirements (size, material, use case), then using CAD tools to build parametric shapes, add functional details, and simulate real-world performance. Start with defining specs (e.g., product fit, assembly steps, branding space) via sketches or client briefs. Use tools like SolidWorks (precision), Fusion 360 (parametric design), or Blender (visual details) to create base geometries (boxes, bottles) and add features like folds, tabs, or label slots. Simulate assembly, material stress, or user interaction to validate functionality before physical prototyping. For beginners, start with simple projects (e.g., a square gift box) in free tools like Tinkercad or Fusion 360—focus on matching real-world dimensions to practice accuracy.
