[TRNSYS-users] prebid: how much orientations are possible?

[David Bradley]

Marielle,
  I am not aware of a limitation on orientations in TRNBuild but I would 
highly recommend simplifying your building as much as you can or at 
least start with a few orientations and then add more instead of 
starting with a whole lot of them. For the external shading by far away 
objects, Type67 is the one to use (Type67 is just an improved version of 
Type68). I would recommend skimming the 05-Mathematical Description of 
the Type to understand what it is trying to do. There is also an example 
in the ..\Trnsys16_1\Examples\Shading directory.
Kind regards,
 David
