[TRNSYS-users] Error generating shading matrix

   There is a limit of 999 surfaces in a TRNBuild model. I do not think 
that there is a limit to the number of surfaces that you can have in one 
zone; the limit is on the entire model. I had a project some time ago in 
which I had to combine a lot of windows together because there were so 
many individual windows that it sent my project over the limit. I 
believe that Transsolar is working on a solution to the problem.
