(...) UPDATE! It _is_ part of a sphere, I just realized, a sphere having a radius of "the square root of 2"! This primitive is one octant of that sphere with three faces "planed/smoothed off" so that the resulting object will fit inside a cube (...)

It is not part of a sphere. It can be thought of as a virtual cube which has had one corner sliced away in a curved fashion. Or to put it another way, it is the grey area in this image: "(URL) radii are "1", and its angles are 90 degrees (i.e., 1/4 (...) (26 years ago, 15-Sep-00, to lugnet.cad.dat.parts.primitives)

Is that food enough? Also, what extra steps (if any) do I need (...) (26 years ago, 15-Sep-00, to lugnet.cad.dat.parts.primitives, lugnet.cad.dev)

Hi, While encoding the Arm piece for the Minifig Skeleton, I encountered something for which I needed a primitive (and I couldn't find anything like it among the existing primitives). At the "wrist" of the Skeleton Arm, there are four (...) (26 years ago, 14-Sep-00, to lugnet.cad.dat.parts.primitives)
