If you want to "extrude" a 2d polygon, you might want to
try using the prism object.

Here is a prism example that makes a hexagon with depth:

prism {
  linear_sweep
  linear_spline
  -0.1,  // These two numbers ...
  0.1,   // ... control the extrusion.
  7,     // number of points
  <-1, 0>,   // first point
  <-0.5, sqrt(3)>,
  <0.5, sqrt(3)>,
  <1, 0>,
  <0.5, -sqrt(3)>,
  <-0.5, -sqrt(3)>,
  <-1, 0>  // to close the shape, last point = first point
  pigment { color rgb <0, 0.5, 1> }
  finish { ambient 0.3 diffuse 0.7 }
}
