The present article analyzes the activity and results of students during a seminar related to a technical subject, Building Construction, studied in the first year of the Furniture and Interior Design department at the Faculty of Architecture and Urbanism of Timișoara. In previous years, wooden models were created to understand roof trusses. To simulate deformations and to better grasp the overall behavior of the truss, the use of a flexible material for the model was attempted for the first time. The study suggests that creating models from flexible materials allows for a better understanding of how trusses function, both at the element level and as a whole, enabling visualizations of deformations without the risk of damaging the model. Additional benefits come from the lower hardness of the material, making joint processing easier. The faster work pace leaves more time for discussions during class. This type of modeling can serve as a study foundation for developing structural models of spatial structures, which can be intuitively understood and help students make decisions regarding the construction of wooden structures.
