+=== Optimization of layup ===
+Use the button {{en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam:show_cs_optimization_button.png?170&nolink}} to display the window for layup optimization.

+With the help of this tool, the possible layups can be determined for the given system and load situation. The optimization can be restricted with regard to producers, number of layers or by means of limits for the panel thickness. Furthermore, outer cross layers or double layers can be included or excluded. With the option "Vibration verification according to EN" the base document is included in the vibration check or not.
+With the buttons "Start" and "Stop" the calculation is controlled. Please be patient, depending on the selected parameter the calculation may take a little longer.
+The possible setups are then displayed in the table and the selected setup can be transferred to the main window by clicking the "Choose the selected cross section" button.

-By choosing "Fire above" and/or "Fire below" in the tab "Fire" a structural fire design has to be carried out. The "Fire duration" is specified in minutes and can be increased (or decreased) by increments of 30 minutes by pressing the up (or down) arrows, or defined by entering a specific duration between 0 minutes and 240 minutes in the allotted box. By ticking the box next to "Fire protection" a layer of fire protection is added to the plate, but the effective protection time of the protection layer needs to be defined.

Furthermore, the position ("above" and/or "below") must be declared and the parameters t<sub>ch</sub>, t<sub>f</sub>, k<sub>2</sub> and k<sub>3</sub> must be specified. In case the failure time of the fire protection system is equal to the time until the protected component starts to burn, the option "t<sub>f</sub> = t<sub>ch</sub>" shall be checked.
