Looking at how the geometry is layed out, I think you've hit a limitation in
LDView's smoothing algorithm. In other words, the lack of smoothness is
caused by a problem with LDView, not by a problem with your layout.
The basic cause of the problem is that the two 2-4ndis primitives meet at a
point. My smoothing code smoothes edges. This is an obvious place where my
code produces incorrect results. Unfortunately, I'm not sure I'm going to
be able to fix the current smoothing algorithm to handle this case. I will
look into it, though. First I have to figure out exactly what it is doing.
While I'm not too surprised that a problem shows there, I'm a little
surprised by the form of the problem. I would actually expect the problem
to be more evident in your helmet on top of the dimple.
