To rotate a 3D model in 3D space, use a 3D software’s rotation tool to adjust it around the X (forward/backward tilt), Y (left/right turn), or Z (spinning) axes—each controls a distinct direction.
Follow these steps: 1. Select the model. 2. Activate the rotation tool (often marked by circular arrows or labeled "Rotate"). 3. Drag axis handles in the viewport or enter precise angles in the software’s properties for accuracy.
For beginners, try free software like Blender. Practice with simple shapes, starting with small adjustments to learn how each axis affects orientation before complex projects.
