How to Develop a City and Guilds Plinth Using Triangulation | Sheet Pattern Development Tutorial

In this video, you'll learn step-by-step how to develop a plinth using the triangulation method, a fundamental technique in sheet metal pattern development. city and guilds .Whether you're working on HVAC duct transitions, architectural elements, or metal fabrication projects, this tutorial will guide you through creating an accurate flat pattern for a square-to-square or square-to-round plinth.

   • Pattern development series  

We cover:
✅ How to draw the plan and elevation views
✅ How to divide the plinth surface into triangles
✅ How to find true lengths using auxiliary views
✅ How to lay out and connect triangle patterns to complete the development
✅ Pro tips for accurate measurements and layout

Perfect for sheet metal workers, fabricators, engineers, and students in mechanical or fabrication training programs.

Tools Used: Compass, divider, ruler, drawing board
Techniques: Triangulation method, true length calculation, flat pattern layout
