In the case of steel cross-section the program allows for introducing the user defined cross-section. Only the shape of cross-section has to be specified in the dialog window. The type of material of the cross-section is selected similarly to other cross-sections (rectangular wall, pile wall, sheet pile…) from the "Catalog of materials", or defined in the "Editor of materials". The type of cross-section (beam) is selected in the "New beams" dialog window.
