Thanks to all, (Grin) all the information you post here is invaluable...

I went to boxxes trying the same thing and I ran into a snag...


// camera position
camera {
  //location <5,-15,-20>
  location <0,0,-30>
  look_at <0,0,0>
}



// light
  light_source {<15,-15,40>
  color rgb <1,1,1>   }
  light_source {<-5,15,-40>
  color rgb <1,1,1>   }

//horizontal center
   difference {
//By using the 'difference' I want to weave the horizonal box underneath the
verticle box
//This works well when using 'tubes'
      box{
          < -6.0, -1.0, -1.00 >, < 6.0, 1.0, 1.00 >
          //scale     <.5,.5,.5>
          pigment { color rgbf <1,1,1,.0> }
      }

//center black out
      box{
          < -1.2, -1.0, -1.00 >, < 1.0, 1.0, 1.00 >
          //scale     <.5,.5,.5>
          //rotate    <0.0,0.0,0.0>
          translate <0.1,0.0,0.0>
      }
   }


//verticle center
      box{
          < -1.0, -7.0, -1.00 >, < 1.0, 7.0, 1.00 >
          //scale     <.5,.5,.5>
          pigment { color rgbf <1,1,1,.0> }

      }
//It works well to this point but if I add any other boxxes...

// if I add these boxes, then I loose the weave effect I had and a blacked out
box appears.
// Using tubes, this effect works but when I went to using boxes, I run across
this problem.
// I can't seem to find what I am doing wrong

       }
