< The axis and two radii of a torus >
The surface is represented by outlines. Only the visible part of the outlines is displayed so that the screen drawing is simplified. The visible part changes depending on the view direction as shown below.

in
order to create tori, each of which has an axis and two radii. The axis
is defined by two points. The texts entered for "Radius 1" and
"Radius 2" define respectively the radius r1 of the small circle
and r2 of the large one as indicated in the figure below. The texts can
be entered before, after or during inputting the axis points. Modification
mode is automatically activated right after a torus is created. And, its
center and the second point can be modified consecutively in the same
way as explained for "Sphere by radius."
