I'm trying to create a measure that allows the user to set the U-Factor and SHGC by direction of the façade (North, South, East, West. I did this with the window/wall ratio by getting the azimuth value from the model's surfaces then calculating the absolute azimuth. I could do this because azimuth was a method for the surface object. However, the U-Factor and SHGC are attributes of a SimpleGlazings object which does not have an azimuth method. How could I set these values by direction for the SimpleGlazings object?
