You need to convert the file generated by Autocad or SketchUp. From Autocad, export as
DXF. A good
tool to do that is PoseRay, it's free.
What POV Ray does, is to interpret a formated text file that describe your scene. That
text file
describe several objects. For each pixel, it evaluate if "something" is there. That
something
(object) is atributed a texture, possibly some reflecivity and/or transparence.
You can add various lights. Those lights can be point lights, spotlights, parallel
(simulating
extremely distant light sources, like the sun). A spotlight or parallel light need to
be oriented
toward some point. Each light have it's own intensity, color and fading (no fading by
default).
A good start is to go trough the tutorial that comes with any distrubution. There is
also a very
good documentation, read it. You also have various sample scenes (all those *.POV
files) that show
you various techniques.
