This tutorial demonstrates how to distribute tree proxies on referenced positions with Grasshopper, using the imported DpFieldmap data (imported during previous tutorial [Part 1]). It also demonstrates a method of how to achieve, with Grasshopper, a method of scaling the placed tree proxies depending on their proximity to their closest neighbour.

As of HT21, Rhino 6 is installed in the following: ARCPLAN, CADLAB-REMOTELAB, XW343-REMOTELAB, and XW41-REMOTELAB. (Check https://www.kth.se/en/student/studier/it/campus/computer-rooms/lista for current status.)
