[Radiance-general] Simulating Perforated Metal

[dela]

Hi everyone!

I'm trying to simulate perforated metal and would 
like to know if anyone knows of any examples where 
this has been done.  (or if this has been discussed 
in a previous digest)

I suppose one way to do it would be to have a metal 
plane and array a series of antimatter spheres which 
would subtract holes in the metal.  Seems like this 
would work, but is perhaps not the most efficient way 
to do this.

Thanks in advance for any help.
