First, I created the grid system and the attractor point. Then, I created the other grid system above the first one. However, I didn’t know how to separate the z value from the list so that I can arrange height for each object. After a couple of hours of struggling, I asked for help and learned which function I can use for that. Then, I followed the videos on Canvas to do height calculations. It was a a bit challenging to find good values for the offset parameters. Then, I created the object and painted it to red since it looks like Isengard from LOTR. The only part that was so confusing is that why we have to create both the cylinder and the mass cylinder while one of them is enough to get the same structure. I guess we’re doing it to transfer it to Revit however I am still confused about that.
