Making the Helix Bridge with Grasshopper, part 05/15 (Grasshopper Tutorial)

In this tutorial I will show you how to create the Singapore Helix Bridge using Grasshopper. During the tutorial series, I will explain the methods we will be using along with other challenges we will come across. The goal is to use logic combined with grasshopper components to build up a parametric model that can adapt to our initial input.

Part 05: In this part, we will build our inner helices. Since the inner helices are built using two radii, we will use if/else expressions to generate a culling pattern which we can then use to select the correct points that ultimately make up the inner helices. #HelixBridge #GrasshopperTutorial #Parametricks ... https://www.youtube.com/watch?v=WiaAuUV2-GE
