[Radiance-general] How to parse room dimensions from .rad model ?

[Vaib]

Thank you Dr.Greg. It makes sense now.

I am just curious to know your opinion on changing the site's North by
rotating the Sky. Do you think it is a good practice? Because on rotating
the building/room, one cannot take full advantage of other good programs
such as getbbox and/or getinfo -d.
