How to Create a 3D Model from image | Trace picture | Convert Image to 3D part | FreeCAD Tutorial 3

🛠️ Learn how to turn a 2D image into a precise 3D model using FreeCAD! In this tutorial, I’ll guide you step-by-step through tracing an image, fixing sketch errors, and converting it into a functional tyre defect gauge—a tool used to inspect rail wheel wear. 📥 Download the reference image & FreeCAD file: [Insert Link] What You’ll Master 🔹 Image-to-3D Conversion in FreeCAD: ✅ Importing & calibrating reference images (exact scaling) ✅ Advanced tracing techniques (Polyline tool, arc modes, constraints) ✅ Fixing broken sketches ("Wire Not Closed" error solutions) ✅ Extruding 2D sketches into 3D parts (Pad tool) ✅ Adding professional touches (fillets, chamfers) 🔧 Key Tools Used: FreeCAD Part Design Workbench Polyline Tool (with tangential arcs for smooth curves) Image Calibration (for real-world dimensions) Fillet/Chamfer (for realistic edges) ⏱️ Tutorial Chapters: 00:00 - Intro: Why trace images in FreeCAD? 01:30 - Importing & scaling the reference image (critical step!) 03:45 - Tracing the outline (pro tips for accuracy) 06:10 - Handling arcs & complex curves 08:25 - Debugging open sketches (must-know fixes!) 10:40 - Extruding into 3D (Pad tool settings) 12:15 - Finishing with fillets/chamfers 13:00 - Exporting for 3D printing (STL) 💡 Pro Tip: Struggling with tracing? Pause at 03:45 to see how I use the Polyline M-key modes for perfect curves! 🔔 Subscribe for more FreeCAD tutorials: [Channel Link] 📢 Question?
