<p>Thin-walled cold-formed steel sections are widely used in structural design. These sections, however, exhibit inestabilities that are caused by compression stresses when a structural member bends. For this reason, is necessary to know the effective values of the geometrical parameters of these sections, such as area section and moments of inertia. In addition, it is not recommended to choose open-shaped sections to sustain torsional loads, mostly if they are thin-walled sections. When designing a structure with thin-walled, open-shaped sections, it is necessary to use geometrical parameters such as torsional modulus, warping modulus, etc. In this job, an application designed in MatlabQ<sup>c</sup> is presented in order to obtain such geometrical parameters. The geometry is discretised, and the algorithms are described. This application, implemented in a graphical way, is aimed to the students of subjects related to mechanical or industrial engineering.</p
