I made a leg with:

- outlines behind the colored region, so that it looks like it is all fused together (as shown in my thread “four kinds of limb joint”)
- The outline tapers to zero width on top and bottom of each part, in case you want to make it visible in front of another limb
- the knee is articulated on top and bottom. I discovered it is the only way to make a leg flex large angles
- 6 pin bones (2 for thigh, 2 for knee, 2 for shank).
- Foreshortening: you can make the thigh or the shank shorter, and the joints will keep the circular shape, thanks to the pin bones
- circle guides, in case you want to increase the width of the sections, you can edit the limbs correctly
- “logic” in the thigh, so when you increase the circles’ radius, the thigh shape grows with it
- if it gives you more problems than advantages, look for the vertices converted to link or scale, and convert them to composite to break the link
- pay attention to the side view and the visible outline in the knee fold. Study the order of the colorfill and the ouline layers.
