Torus: what's an easy/best way to create it?

What’s the easiest/best way to create a torus shape with a specific inner diameter?

Hi @DrBenedictPorkins Welcome to the Forum.

This is one way to do it.

Sketch a Circle, the Diameter of which, minus the Diameter of the Torus Section/Profile, will equal the Internal Diameter of the Torus.

Use Add > Construction Plane > choose option Perpendicular to Curve at Point

On the Construction Plane Sketch the Profile of the Torus Ring:

Use Tools > Sweep to form the Torus.

In this case 80mm Diameter - 10mm Diameter = 70mm Diameter
