I am using Prism to generate  a complex x-z shape with sloping  outside
walls.

The problem is that the program always wants to use the 0,0 axis as the
reference for the slope origin. I then finish up with some walls leaning in
and some walls leaning out.

This is the code that I am using.

prism {
  conic_sweep
  linear_spline
  1, 1.5, 6,
  <0,0>,<5,2>,<3,6>,<1,5>,<2,3>,<-1,2>
    scale <1,-4,1>       // slopes walls outwards
    translate <0,4,0>   // relocates to origin
   pigment {color Green}}

Anybody got any ideas how to solve this?
