How To 3D Model Tricky Fillets (Plasticity Tutorial)

In this tutorial, I’ll show you how to manually create beautiful fillets on a complex symmetrical surface using Plasticity 3D. We’ll pick up where we left off in Part 1 and dive deep into advanced manual fillet workflows. You’ll learn how to rebuild curves, use pipes for cutting geometry, create smooth Y-blends, and patch everything seamlessly for clean topology and stunning reflections. This is an advanced tutorial — ideal for those looking to master surface modeling in Plasticity and push their design work further. At the end, I’ll also show you how to export the model into Blender or Cinema4D or Blender 00:00 – Intro & What You’ll Learn in This Tutorial 02:17 – Why Automatic Fillets Fail on Complex Surfaces 04:09 – Rebuilding Curves & Cutting Geometry with Pipes 10:04 – Patching Manual Fillet Areas (Y-Blends & Lofting) 19:42 – Cleaning Up Topology & Completing the Form 23:01 – Exporting to Blender or Cinema 4D for Rendering
