Spatial geometry is one of the multi-purpose fields of mathematics and is tightly linked to the development of mathematical and intellectual thinking. Spatial thinking is necessary in various areas of life such as civil engineering, mechanical engineering, interior design, graphic design and other. At present, teaching spatial geometry is mainly based on mathematical logic -- precise wording and arguments -- rather than sketches and models. This mode of teaching allows teaching and defining definitions, axioms, or arguments, but does so without sufficient reference to the spatial aspect, which is characteristic of geometry. In this article, we examined if the use of technological tools to display 3-D geometric objects during engineering studies improve the students' spatial thinking.
