in this example i begin learning to draw bones using scripting in blender on a quadruped and biped.
1. draw straight chains for arm 4 bones,leg 2,foot 2, pelvis 1, spine 4,headnNeck 2, root single bone, no parenting, fixed positions, no naming
2. 1. with parenting
3. draw straight chains for quadruped spine 3, legs quad 2, foot quad 2, arms 3, no parenting, fixed positions, no naming
4. 3. with parenting
5. 2 with naming
6. 4 with naming
7. draw jaw,headnNeck,upSkull chains, fixed positions
i basically wrote a few draw functions for the various parts of the character. i also added some naming and parenting functions for bones. The examples use fixed positions so extending this to be able to use saved bone positions would be nice - that way it can be customized to a particular character. also would be nice to begin working on a control rig layer for various parts.
Hope you find this helpful,
Happy Sketching and Scripting!
