i’m trying to determinate the percentage of curtain walls length compared to total length of walls at every orientation and at every level (in particular, level 1 and 2). I used the component Wall.NorthSouthEastWest from Rhythm repository, but there is some issue according to nested lists. In the example above, for the east exposition, there is a curtain wall only at level 2, so for the east output component returns “empty list” for the first level and “wall ID” for the second one. The problem is that the two results are on differents list levels (@L3 “Empty list” and @L4 “Wall ID”).
How can i resolve this issue?
