Excel macros can streamline the creation of profiles from points and splines in 3DEXPERIENCE. By using the GSD_PointSplineLoftFromExcel found in the command folder, it becomes possible to import data from Excel to generate complex profiles, such as NACA airfoils, with ease. This approach not only saves time but also enhances accuracy, significantly improving design workflow efficiency. 3DEXPERIENCE GSD CATIA
