If you are looking to acquire skills in Grasshopper, we would like you to join our Computational Design with Grasshopper course. This course is for design professionals that are looking to learn the concepts and features of Grasshopper that are easy to follow at your own pace.

The purpose of this course is to explore forms and design possibilities with Grasshopper’s tools and understand their relationship to Rhino. ** Watch a few of the projects you will be able to create after the completion of this course!** The class should help you improve your workflow by covering modeling geometry, data structure, general concepts, data types, data matching, lists, trees, and of course, tons of creativity. It will provide you with a functional understanding of Grasshopper and parametric design thinking. The advantages of using Grasshopper in preliminary design and concept development come to life in numerous real-life examples throughout the course.
