Infinity Symbol Assembly

The infinity symbol (∞) looks deceptively simple as a sketch, but building it from steel tube is a different story. Every segment meets at a compound angle — the "loops" connect through three dimensions, and the crossover at the center demands a miter combination that's nearly impossible to visualize, let alone calculate, by hand.

Open this project in FitUp Assembly Builder to see the full 3D assembly laid out and ready to go. Rotate it, inspect every joint angle, then generate your own build packet with cut lengths and miter templates sized to your material. Change the tube diameter or wall thickness and the whole assembly updates automatically.
