To scale a layered 3D model, select the target layer(s) in your 3D software, then use the scaling tool (often labeled “Scale” or with a cube icon) to drag for free resizing or input numerical values for uniform (all axes) or axis-specific adjustments.
This lets you adjust individual or multiple layers without altering the entire model—ideal for refining details like product parts or character accessories.
For precision, use exact percentages (e.g., 50% for half size) instead of dragging. This keeps layered elements proportional, which is key for complex designs.
