[TRNSYS-users] Re : About Shading masks (type 67) and Overhang and wingwalls shading (type 34)

[Diego A. Arias]

Dear Morice,

I prepared a tutorial on how to connect Type67, 34 and 56.
Go to 
http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/connecting34_67.pdf
Please let me know if you have comments about the tutorial.
Best regards,

Diego
