Ok..... here it goes... well.... its got some comments 'cause I just cut and
paste from the tutorial... and I added my own values :)

prism {
cubic_spline
0, // sweep the following shape from here ...
1, // ... up through here
21, // the number of points making up the shape ...
< 2, 0>, // point#1 (control point... not on curve)
< 0, 0>, // point#2 ... THIS POINT ...
<1, 1>, // point#3
< 2, 0>, // point#4
< 1,-1>, // point#5 ... MUST MATCH THIS POINT
<0,0>,
<1,1>, // point#6 (control point... not on curve)
<1.75,0>,//Start of Second shape
<0.25,0>,
<1,0.75>,
<1.75,0>,
<1,-0.75>,
<0.25,0>,
<1,0.75>,
<1.5,0>,//Start of Third Shape
<0.5,0>,
<1,0.5>,
<1.5,0>,
<1,-0.5>,
<0.5,0>,
<1,0.5>

scale<0.25,0.125,0.125>
translate<0,-1,-1>
rotate<90,0,0>
}

Thanks !!!!!
