The cross section can be defined by the user or by choosing a typical cross section of a proprietary CLT product. Des Weiteren besteht auch die Möglichkeit eigene BSP-Aufbauten abzuspeichern. FIXME The elements are subdivided by the number of layers. | The cross section can be defined by the user or by choosing a typical cross section of a proprietary CLT product. There is also the possibility to save own CLT cross sections in a library. The elements are subdivided by the number of layers. |
| |
If a user-defined cross section is entered, the thickness and orientation of each layer can be changed. Furthermore, the material can be changed for all layers. The thickness of each layer has to be within the range of 6.0 mm to 45 mm. In the case of proprietary CLT products, the strength class of lumber and the orientation can be changed. If the orientation is changed, the whole cross section is rotated. | If a user-defined cross section is entered, the thickness and orientation of each layer can be changed.

The width of the CLT plate strips can be also defined in this field. The default value is set to 1 m. The thickness of the CLT plate is calculated automatically based on the thickness of the single layers. | The width of the CLT plate strips can be also defined in this field.

| === Optimization of layup === |

| {{ en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam:cs_optimization.png?600 |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. |
