This is part of the series of 30 exercises developed during the E3D+VET program. The aim of this Erasmus+ program is the immersion in 3D printing of VET centres (website: ). The model consists of 7 parts. First, there is a base plate that represents the environment. This is made of a cardboard with 100x100cm. In the next step, the pyramids are created, whose dimensions correspond to the truth in the scale. After the pyramids, which resemble an isosceles triangle, have been established, the exact points of view are determined on the base plate. The dimensions are predetermined so that the student can recognize the center of the pyramid on the basis of given dimensions / distances or with the help of the coordinate system, and thus can place the pyramids.
