The "button" at the top is not a button, but a rocker. If you click it at the right end, the program advances to the next input; if you click it at the left end, the program goes back. This is clearly indicated by the label in the middle. There you can see which field-lean-to rafter entry number you are currently viewing out of the total. This also allows you to define field-lean-to rafters for different layers. In the next field you again select a lean-to rafter setting (as with individual rafters). This defines all dimensions and connections for the field-lean-to rafter. Here too, the setting can be changed arbitrarily via the browser button. If the setting then no longer matches the saved setting from the standard lean-to rafter input, the name of the setting is written in parentheses. In the next four fields you can set fixed distances to the layer edges of the element boundaries. The first field-lean-to rafter will be located at this position. Using the checkboxes to the right of the input fields, however, you can determine whether a lean-to rafter should be generated at this position or not. For example, if you want an even distribution between the individual rafters at the element edges, you enter the individual rafter width for top and bottom here and disable the generation of rafters (the first and last field-lean-to rafters) here. With the next fields you determine the subdivision of the element with the field-lean-to rafters. This can be done either with a fixed spacing or with a variable spacing. --- # 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-feld-schragsparren.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.
