Grasshopper 101: Data Filtering | #05 Filter Mesh Vertices | EXERCISE

Показать описание

EXERCISE: In this tutorial, we practice using Conditional and Logical Operators for Data Filtering. We learn how to create a mesh surface, based on the NURBS surface, and revise the concepts of data construction and deconstruction in Grasshopper

This video is an introductory tutorial for beginners.
