This article describes a computational method aimed at determining and describing the geometric structure of crystalline substances. In the study, using a table compiled on the basis of experimental data, the lattice dimensions, angles, spatial symmetry, and crystal system of the substance are determined according to its chemical formula. With the help of the proposed software solution, the Bravais lattice is depicted in a simplified form, as well as a real unit cell in a geometrically accurate three-dimensional space. In addition, the general distribution of crystal systems is statistically analyzed based on the available data set. The results obtained allow us to study the spatial properties of crystal structures in a visual and understandable form and serve as an effective tool for teaching and scientific research in the fields of materials science and solid-state physics.
