| 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 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. |
| | |
