1. I am using Ecotect export to Radiance. In Ecotect, I placed camera to get
illuminance image, but it seems that the output image shows lux levels on
ground level. It doesn't give lux contours on a task plane (at any level).
Can anyone help me out in getting lux levels on a certain height.
2. does autocad2009 have radout command for radiance export. can anyone hel
p me know about it. thanks. and if any other way where i do modelling in
autocad and export option to radiance?

Once again:
1) create a grid for the room
2) set the height for the grid to your work plane height
3) export to Radiance and make sure to set the option to export the grid as
well
4) execute the *.bat file created by Ecotect
5) load the *.dat file that created by the *.bat file
6) use the Ecotect features to visualise the results
If you need help with Ecotect please contact Autodesk for support.

Radout is not part of Autocad. You have to download and install it. You can
find information on radout on Georg Mischler's page:
I'd say, go the purist way, use radiance on unix
learn the meaning of rtrace.
you can create text files filled with point locations and sensor normals, then with rtrace measure you preferred metrics.
file like
x y z nx ny nz
and then
rtrace -all_the_settings_you_like model.oct < your_grid_of_points > results.out
I am fairly sure that you will find some more guidance here in the old emails or on the internet in form of tutorials.
I may suggest to look a little here, slightly out of date but still very useful:

good luck
