Hi
Thanks for the feedback so far. I had looked up the suggested functions
(trace, vrotate) but hadn't yet had the opportunity to figure out if they'd
be the best tools to use.  If that's all you can suggest, then I'll
eventually get this to work for me.

What I'm trying to build is the surfaces of a rhombic dodecahedron, but more
than just the 3-D object comprised of 12 surfaces: - assume each side is
made from a piece of wood and thereby is a 3-D object in it's own right and
therefore each side is rotated and translated from the declared object at
the origin and must be aligned next to another side(s).

If you have any further hints, I'd appreciate it.

shapes.inc defines a [regular] dodecahedron as follows, this one has 12
sides made of pentagons; "mine" is 12 sided of course, but is 12 rhombi
which I defined as following next.

#declare Dodecahedron =
 intersection
  {plane {-z, 1 rotate <-26.56505117708,    0, 0>}
   plane {-z, 1 rotate <-26.56505117708,  -72, 0>}
   plane {-z, 1 rotate <-26.56505117708, -144, 0>}
   plane {-z, 1 rotate <-26.56505117708, -216, 0>}
   plane {-z, 1 rotate <-26.56505117708, -288, 0>}

   plane {-z, 1 rotate <26.56505117708,  -36, 0>}
   plane {-z, 1 rotate <26.56505117708, -108, 0>}
   plane {-z, 1 rotate <26.56505117708, -180, 0>}
   plane {-z, 1 rotate <26.56505117708, -252, 0>}
   plane {-z, 1 rotate <26.56505117708, -324, 0>}

   plane { y, 1}
   plane {-y, 1}
   bounded_by {sphere {0, 1.2585}}
  }


#declare RhombicDodecahedron =
intersection
  {
 plane { z, 1 rotate <  0,  45,  45>}
 plane { z, 1 rotate <  0,  45, -45>}
 plane { z, 1 rotate <  0, -45,  45>}
 plane { z, 1 rotate <  0, -45, -45>}

 plane {-z, 1 rotate <  0,  45,  45>}
 plane {-z, 1 rotate <  0,  45, -45>}
 plane {-z, 1 rotate <  0, -45,  45>}
 plane {-z, 1 rotate <  0, -45, -45>}

 plane {-x, 1 }
 plane { x, 1 }

 plane { y, 1}
 plane {-y, 1}
  }
