I am trying to process data from Excel into Room Boundary Lines, per level, into an existing model.
The spreadsheet has Column A: Level Name, Column B: DesignScript String. I am using regex to convert the strings to model lines. The lines are then grouped by level.
Everything seemed to be going ok until dealing with the CurveArray(). The closest I got was to use a nested for loop into curvearray, but that produces a flat list. Since I want to put many curves on multiple levels, I need to separate them. I’ve tried dict, enumerate, various indents, but no dice.
Looking at the Clockwork node, it should be easy, as it only uses one for loop to create the CurveArray. Since the NewRoomBoundaryLine method requires a singular SketchPlane and View per CurveArray, is there some kind of list wrangling I’m missing?
