 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.

 The individual objects can also be displayed independently of each other. While only one [[Color3D|base colour]] can be selected in the tree view, different colours or displays can be assigned to each individual object in the list. Double-clicking on the respective object opens a dialogue box for [[Stroke3DExt|settings]] with which the object can be modified.

 **Note**: if the colour of an object has been changed in this way, it can no longer be modified using the general colour selection in the tree view.

-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.
