[Radiance-general] The Three-Phase Method for Simulating Complex Fenestration with Radiance

[Leyla Sanati]

German,

Thank you for your response.
I actually tried exporting the results to excel. However, the huge text
file needs some time consuming editing before the export.
I wonder if we could modify the scripts to pipe each sensor point data into
a separate file with one set of R G B values in each line.
This will save me a lot of time.

Thank you,
Leyla
