At Learn Visual Programming, we aim at creating a thorough guide for using Grasshopper in Rhinoceros. Our main objective is to provide an efficient and pleasant learning experience for both beginners and advanced users. Here you will find explicit video tutorials, comprehensive explanations, and easy-to-follow exercises that foster the understanding of Grasshopper and visual programming in general.

All tutorials are grouped into playlists, based on their topic and required proficiency. To ensure gradual learning, the videos and the playlists are structured in sequential order, designed to be followed consecutively, but are wholesome even if watched separately.


In this exercise, we are going to practice working with indices in Grasshopper. We are going to create text tags for a set of circles using their indices and identify the largest circle on the list by displaying its radius. And we will do that by applying custom mathematical expressions.

Don't forget to check out the introductory tutorial on the Item Index, Member Index, and the List Item components. 

Have fun!
