The paper shows the example of solving some Apollonius’s problems procedure, which is an interesting example transferring of solutions plane problems in the area. The result of solving these plane tasks then calculated as the orthogonal projection obtained stereometric solutions to the plane in which the problem is submitted. The solution can be constructed as a means of descriptive geometry, as well as using CABRI 3D software that facilitates the solution Apolloniových tasks without the use of circular inversion.
