Welcome back to a series of GenerativeComponents Quick Tips QT#2 is all about using excel to update polygon colours in GenerativeComponents. Special thanks to Volker Mueller for his on going support and tips on more efficient workflows. In this video I show some tips on how to setup a polygon array for testing, then how to link the polygon colour property to excel data for dynamic updates. I will also show an example of how this workflow might be put into practice on a building facade.
