# 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.
