# PO\_AddRadialGrid Add radial sensor grids for running Radiance grid based simulations. Use "Pollination" command to open Radiance Object Manager to check and edit each sensor grid. ## Options * **GridSize** Space between any two sensor points. (in Rhino's unit) * **Offset** Offset distance from the input geometries. (in Rhino's unit) * **Directions** A positive integer for the number of radial directions to be generated around each position. (Default: 8) Notes: * The input geometries can be Rhino surfaces, rooms or orphaned faces. * For rooms, only sub-surfaces with floor type will be used for generating sensor grids. * This type of sensor grid is particularly helpful for studies of multiple view directions, such as imageless glare studies. --- # 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/pollination-commands/alphabetically/po_addradialgrid.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.
