2. Positioning the Mesh: Adjust the model\"s position in the scene to facilitate symmetrical rigging. Set the model\"s origin point at its base for more natural movements.
3. Creating the Armature: In Blender, a rig is known as an armature. Add an armature and position it within your model. Use the X-ray mode to see the armature through the model.
4. Defining Bone Hierarchy: Start from the main bone (the center root) and create branches for limbs. Use extrusion to add new bones for the model\"s extremities.
5. Mirroring for Symmetry: Duplicate and mirror bones to the opposite side for symmetrical parts like arms and legs. Ensure all bones are correctly connected to create a coherent skeleton.
6. Combining Armature and Mesh: Parent the mesh to the armature using \"With Automatic Weights\" for Blender to calculate the influence of each bone on the mesh.
7. Weight Painting: Refine how each bone affects the model by adjusting the weights. This step is crucial for realistic deformations and movements.
8. Animating: With the rigging complete, you can now animate your model. Use keyframing, inverse kinematics, and Blender\"s Non-Linear Animation (NLA) editor for creating animations.

Blender offers comprehensive tools for rigging and animation, including automatic skinning, easy weight painting, and mirror functionality. For complex movements, utilize constraints and drivers to control object properties indirectly or with mathematical expressions.
