Really hoping someone can help me with this.
In the image above I have combined a whole bunch of parameters which leaves me with many sub-lists of strings. What I am trying to achieve is to group each sub-list based on their SolarOrientation. For example I need to know how many walls in each sublist are facing “N”, how many are facing “E” etc. Then I need to add their area values together to give me one value for all of the walls that are facing a particular direction. The part that I am struggling with is keeping the list structure the same.
I cant seem to work out what to do, I have tried a number of approaches, most recently I tried using the List.GroupByKey node but quickly realized that I need to change the length of my list to use this.
Any direction or suggestion would be great.
Thanks very much.
