- Understand dimensions in design: Dimensions are measured sizes (length, width, height, thickness) that control how big each part is.
- Learn about scale and proportion: Scale is how a model’s size relates to the real object. Proportion is how parts relate to each other (e.g., a lid must be slightly larger than the opening it covers).
- Apply measurements to functional objects: Use real measurements plus clearance/tolerance so your design works in real life (it fits, opens, closes, and doesn’t collide).
