Typical values range from 3 to 5 meters. * **name** Text to set the base name for the Room2D, which will also be incorporated into unique Room2D identifier. This will be combined with the index of each input \_footprint\_geo to yield a unique name for each output Room2D. If the name is not provided, a random one will be assigned. * **program** Text for the program of the Room2Ds (to be looked up in the ProgramType library) such as that output from the "HB List Programs" component. This can also be a custom ProgramType object. If no program is input here, the Room2Ds will have a generic office program. * **constr\_set** Text for the construction set of the Room2Ds, which is used to assign all default energy constructions needed to create an energy model. Text should refer to a ConstructionSet within the library such as that output from the "HB List Construction Sets" component. This can also be a custom ConstructionSet object. If nothing is input here, the Room2Ds will have a generic construction set that is not sensitive to the Room2Ds's climate or building energy code. * **conditioned** Boolean to note whether the Room2Ds have heating and cooling systems. ### Outputs * **report** Reports, errors, warnings, etc. * **room2d** Dragonfly Room2Ds. --- # 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.ladybug.tools/dragonfly-primer/components/0_create/room2d.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.
