I start to wonder about the use cyli/cyls primitives within the arm parts: when they are rendered with primitive substitution, this result in gaps in the arms, very noticeable. Maybe we should inline them...

Yes, I was looking at them yesterday. Don't like them.

And maybe we could also remove that kink inside the elbow? It looks like it has been "forced" to fit the primitives.
I was planing to use your knob in all minifig arm parts. Maybe it is time for a reshape, before we start making patterned arms. Gerald, any opinion?

I must agree with Philo, due to the primitive substitution visible gaps appear when rendering the arms., Inlining some of the prims would for sure benefit the final result

What do you mean with that: that kink inside the elbow

See the kink on left image: http://www.brickshelf.com/gallery/Philo/misc2/3818.png
I'd prefer to see the surfaces spared from the kink into a smoother outer elbow surface
