To do so, select the roof surface and the same dialog box that appears when entering element joints will open. With the switches "Division along X" and "Division along Y" you select the direction of the new element joint and then click at the position where an element joint is to be added. The structural model does not change at this point (after exiting the function the modified elements lose their components). Once all element joints have been added, select the "Recalculate elementation" function and then all components will be regenerated. ### Move element joint Each element joint can be moved afterwards using the "Move element joint" function. To move, select the element joint to be moved and enter the distance by which it should be moved. An arrow on the element joint indicates the positive direction of movement. Moving does not yet affect the components. This is achieved by recalculating the elementation. ### Delete element joint Each element joint can be deleted individually. To delete, select the element joint to be removed. The components of the elements to the right and left of the deleted element joint are automatically removed. You can now add a new element joint or recalculate the elementation with the new situation. The two former elements are then treated as a single element. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.dietrichs.com/dietrichs-intelligent-documentation/docs-de-en/design-program/modellbereiche/dach/systeme/dachelemente/dachelemente-elementstoss-erganzen-verschieben-loschen.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
