# Consider Recesses for the Sheathing Claddings in HRB can align to windows and doors as described in detail above. At the left and right edges of the corresponding layer contour of the opening, field boundaries then arise for that cladding. The cladding is terminated and restarted at each of those locations. Since version 19.01, niches can optionally also be taken into account. Because this is typically not true for all niches, an identifier is placed on the niche itself for this purpose: *consider HRB cladding like windows*: Yes/No. When set to Yes, the cladding responds to this niche as it would to a window; the prerequisite is that the niche also generates a layer contour in the cladding layer. In this way, the cladding can, for example, align to a large mirror niche while ignoring the niche (HrbReference) for the inspection flap. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.dietrichs.com/dietrichs-intelligent-documentation/docs-de-en/holzrahmenbau-kompendium/prinzipien-des-hrb-systems/beplankungen-ausrichten-zusammenfassen/nischen-fur-die-beplankung-berucksichtigen.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
