Thanks to the feature of subsurf-ing, a common method of animation is to extrude parts of a simple geometric figure into the shape of the final model. An armature is then added to the limbs to enable movement.
Does Blender provide for centering a bone along a extrusion? Then I could simply select points, extrude them, and tell Blender to place a bone(s) along the geometric center of the extruded limb?
Such a feature would be an immeasurable boon to precision-obsessive animators like myself.
