Formcode is defining the shape of cross-section and how it is oriented according to used LCS. Due to defining the formcode for CSS, exchange of SAF files between applications that are differently handling LCS is possible.
Formcode of manufactured cross-section, together with the attribute "**LCS of cross-section**" from the sheet [Project and model specification](../getting-started/project-and-model-specifications/#project) is defining the exact orientation of cross-section in the model.
Formocode set to "**0**" means that receiving application won't do any action ensuring the proper positioning of CSS.
