It allows the user to create a solid torus which has the information of two radii and the angle. By defining two points to set the major radius and the minor radius on the working window, the user can make it easily. In order to modify the geometric information, the user should open the Torus page after entering Body Edit Mode. For references, when selecting two points, the major radius is calculated automatically, and the minor radius should be defined as 25% of the major radius. At this time, the angle is 360 degrees as default.
