This paper presented 3D dynamic models representing two fundamental methods in descriptive geometry changing planes and revolution. The objective is to display the true size of the objects analyzed in 3D space and their adjacent views. Despite the relevance of the topics in descriptive geometry, these are contents that students struggle to consolidate. Thus, it has happened because the widely applied resources in the teaching-learning process do not support the procedures required to understand them. To fulfill this demand, we built 3D dynamic models regarding the line changing planes and the plane revolution in GeoGebra. After creating the models, a survey questionnaire was sent to specialists, for accessing and evaluating. As a result, the answers indicated that the 3D dynamic models conveyed the information regarding descriptive methods effectively. Additionally, above 60% of the participants intend to adopt the dynamic models in their classes.
