Precise geometry vs fine-shading topology?

[Magnus Forsberg]

I've not checked closely, but in this configuration they should work easily. Keyword is "interpenetrating": since this part is not transparent you can hide unwanted portions of primitive geometry inside the part.

It depends on what we want here.
A smooth surface is possible as Philo say, using cyls primitives. Also in hi-res.
A smooth surface and a non-crooked edge line between them, is not possible, due to the cylinders beeing of different dimensions.
