# Create Shade or Context ## From Rhino Geometry We are supporting different type of shades: aperture/door shades, room shades, building shades, and site context/shades. In general, there is no difference among above types. However, they are useful to be organized when you want to convert your model to ASHRAE 90.1 baseline model with our Pollination recipe or you want to study an annual daylight simulation for LM-83 standard (LEED daylight credit). All shades, except the site context/shades, have to be removed or controlled dynamically for above standards. Assigning shade geometries to a correct type will make your future work easier. {% embed url="" %} ## Add shades parametrically from Grasshopper Typically creating shade geometries for all windows may take some time if you are not familiar with Rhino, but it becomes very simple if you want to generate shades for all windows parametrically in Grasshopper. Once you created all shades in Grasshopper, you are able to bake them back to Rhino so they can be part of your existing model. *Note: be aware of duplicated geometries in Rhino when you bake multiple times.* {% embed url="" %} --- # 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.pollination.solutions/user-manual/rhino-plugin/modeling-best-practices/add-shade-or-context.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.
