The house contours are then re-centered and intersected with each other. Free roof surface deformations are lost in the process. ### Impacts: The intersection priority can be used to influence how the roofs are intersected with each other. If both roofs have the same intersection priority, they intersect each other: when two roof surfaces penetrate one another, each is cut by the other. The portions of the roof surfaces that lie beneath the other roof surface are removed. If one of the two roofs has a higher intersection priority (i.e., a smaller number), that roof is not cut and remains as it is. The roof with the lower intersection priority (i.e., a larger number) is cut against the other roof. The portions of the roof surfaces that lie beneath the roof surfaces of the other roof (with the higher priority) are removed. A special case is the intersection priority '0'. A roof with this intersection priority is not considered during an intersection. It is neither cut itself nor does it influence the intersection of another roof. --- # 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/dachbearbeitung/verschneidungsprioritat.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.
