Three functions are available to select the ceiling panel. If no ceiling is selected yet, the 'Storey' selection appears automatically when this model area is opened. ## Ceiling selection - Storey If no ceiling panel is active when the model area is opened, or if you wish to change the current storey, the 'Storey' function is invoked. The list displays all storeys with a preview of their floor plans. After selecting the storey, the 'List' function is invoked automatically. ## Ceiling selection - List In the 'List' dialog the ceiling panels are listed and selected in a list. For clarity when multiple ceiling panels exist on a storey, the ceiling panel selected in the list is highlighted in color in the dialog’s preview window. ## Ceiling selection - Choose The 'Choose' function displays the floor plan of the current storey and the current ceiling panel can be selected graphically with the mouse. --- # 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/deckenkonstruktion/deckenwahl.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.
