In the framework of the project EFOP-3.6.1-16-2016-00022 00022 „Debrecen Venture Catapult Program”t workshops are held in secondary schools in order to show for the students that the precise knowledge about the mathematical backgrounds is an important part of the engineers works. We give lot of examples in our environment for appearing of quadratic surfaces; for instance in architecture, in mechanical engineering life (gear– wheels, twist drills,…etc.).The development of geometrical spatial ability happen by the help of using 3D animations, moreover we investigate the changing of the shape of surfaces by mathematical shoftwares. We are going to built hyperboloid of one sheet and hyperbolic paraboloid.
