The design and visualization of the distribution of atoms in a fraction of space through the application of software allows us to increase the understanding of the structure of materials and the elaboration of theoretical propositions. The purpose of this work was to develop a procedure for the application of the GeoGebra 3D software as a tool for designing crystalline structures, from the Mathematics subject for Chemical Engineering students. A workshop called GeoCristal was held to reflect experiences on the use of GeoGebra 3D. Based on a sequence of tasks, the students designed a BCC crystal structure related to alpha iron in the software. The experience demonstrated the usefulness of the software for the design of crystalline structures. It made possible to promote and systematize essential contents of Materials Engineering. Managed to increase students' motivation for Mathematics. The study reflected the importance of the use of ICTs and basic subjects in the training of chemical engineers. [ABSTRACT FROM AUTHOR]
