In this paper we emphasize the usefulness of using GeoGebra and specifically GeoGebra 3D Calculator in the educational process, for first year students, Land Surveying and Cadastre, at the Faculty of Geodesy of the Technical University of Civil Engineering Bucharest. The implementation of this way of teaching in the course Geometric Representations of Topographic Surfaces was initiated two years ago, in a gradual way, in order to support the students to understand well certain concepts. We started with a bibliometric study on this software product, then we showed how we implemented its use in the applied training of students. We have developed as training materials an e-book and a book in classical format, with problems solved both in the classical way and as examples using the software. These approaches have led to better results in the learning process, as well as to a more active involvement of the students during the application classes. Supporting classroom problem-solving with experienced applications significantly improves students' problem understanding. GeoGebra fosters a collaborative learning environment through group investigations, conjecture-sharing, and alternative solution discussions. This helps students develop essential critical thinking, communication, and teamwork skills. Additionally, GeoGebra aids formative assessment; interactive applets allow educators to track students' reasoning processes. Experience in the Geometric Representations course shows GeoGebra motivates learning mathematics overall and reduces anxiety for first-year students. Students became more self-critical of their work, questioning their errors in problem-solving and gaining the opportunity to visually identify those mistakes
