 A sphere is described by the absolute value of the difference between a vector (x/y/z) and the centre of the sphere. For all (x/y/z) on the sphere, this absolute value is equal to the radius of the sphere.
  The radius and the vector (separately for the x, y and z coordinates) can be entered in the **//Spheres//** tab. Clicking on the **//Add to list//** button displays the sphere in the right-hand window. A check is performed to see if the sphere is already part of the list.

+A circle is described by its centre point, a normal vector in the circle plane and its radius. The radius and the vectors (separately for the x, y and z coordinates) can be entered in the **//Circles//** tab. Clicking on the **//Add to list//** button then displays the circle in the right-hand window. A check is performed to see whether the circle is already part of the list.

-The [[Schnitte3D|Determine sections]] function can be used later to determine the intersection points of the objects. Unlike the other graphics, these are not determined graphically, but are actually calculated based on the values entered. The sections determined and saved there can therefore be **//loaded from a file//** and displayed again here.
