Rhino 3D Tutorial: Fix Watertight Meshes & Naked Edges for 3D Printing | Ep.5

Learn how to fix watertight meshes in Rhino 3D and prepare your models for 3D printing step by step. In this beginner-friendly tutorial, Jonathan explains how to identify and repair common mesh problems like *naked edges, mesh holes, and non-manifold geometry* using Rhino’s built-in tools. 👉 Download the project files here to follow along:* https://www.dropbox.com/scl/fo/5s4exw... We’ll go over essential commands such as: *ShowEdges* – visualize naked edges in your model. *MatchMeshEdges* – automatically connect misaligned edges. *FillMeshHoles* – repair missing geometry quickly. *PatchSingleFace* – manually fix complex holes. By the end of this lesson, you’ll understand how to ensure your models are closed, watertight, and 3D-printable. Whether you’re an architect, designer, or beginner learning Rhino, these techniques will help you avoid catastrophic errors when sending files to slicers or fabrication. ⏱️ Timestamps: 0:00 Intro – What are watertight meshes? 0:37 Naked edges explained 1:21 ShowEdges command 2:32 MatchMeshEdges command 3:50 Filling mesh holes automatically 4:55 Manual mesh repair techniques 5:59 Why architects must model solids 6:34 Final thoughts 👉 Subscribe for more Rhino 3D tutorials for beginners. 👉 Comment below if you’ve struggled with naked edges before. #workflows #rhino #tutorials
