Is there a reasonably simple way to create a torus with minimal vertices and faces (that is no artifacts from merging extrusions) with more than 256 segments (in my case 1800 major segments and 360 minor segments) with a major radius of about 900m and a minor radius of about 50m?

    $\begingroup$ It is possible, but this kind of heavy geometry may kill your computer. Are you trying to make a hyperrealistic, ultradetailed donut? ;). $\endgroup$ – Paul Gonet Feb 5 '15 at 19:25

  • $\begingroup$ The computer has enough power to render many more polygons than that (it's already got a few dozen objects with similar polygon counts and scale on screen) - just trying to find a way to construct it that doesn't add excess vertices or polygons and doesn't involve me selectively filling each face - going for the inside half of the torus with a flat exterior so I'm already going to have to manually fill in 1800 polygons $\endgroup$ – CoryG Feb 5 '15 at 21:56

Start by adding a circle, with 360 vertices, a radius of 50, and the Fill Type set to Nothing.
Add circle options
In edit mode rotate the circle along the Y axis by 90°. Then move the circle 900 along the Y axis.

Last add a Screw modifier, with Steps and Render Steps set to 1800. Leave all other modifier settings to default.
screw modifier
You now have a torus with 648,000 vertices and faces; 1800 major segments and 360 minor segments.
