Create 3D Shapes from Rhino to Grasshopper | Beginner Modeling Tutorial

In this tutorial, we’ll learn how to create 3D shapes and surfaces in Grasshopper using geometry imported from Rhino. This beginner-friendly video will help you understand how Grasshopper transforms simple curves into 3D printable models through lofts, extrusions, and sweep operations. We’ll start by bringing curves from Rhino into Grasshopper with the Curve component, and then use Loft to create surfaces. Next, we’ll add Extrude to give the model thickness, control direction with Unit X, and adjust values with number sliders. You’ll also learn how to use Sweep1 and Sweep2 to create tubes and blended shapes from multiple curves, and how to close open geometries using Cap Holes for 3D printing. 👉 Download the project files here to follow along: https://www.dropbox.com/scl/fo/2rini0k2klm0qhnva5u4y/AMgiSkVL3gsn3ZsPPQUVrEc?rlkey=327oxhmdv9q5ms5x8ztwskbco&dl=0 By the end, you’ll know how to: Convert Rhino curves into Grasshopper geometry Generate surfaces with Loft and Sweep Add solid thickness using Extrude Prepare closed, printable 3D models with Cap Holes Timestamps: 0:00 Introduction 0:30 Importing curves from Rhino 0:46 Creating surfaces with Loft 1:14 Extruding with thickness 2:09 Modeling with Sweep1 3:02 Closing geometry with Cap Holes 3:29 Using multiple sections in Sweep1 4:14 Creating complex forms with Sweep2 5:06 Wrap up 👉 Subscribe for more Grasshopper tutorials, Rhino workflows, and architectural modeling guides.
