Grid
surface node
Creates a plane.
The plane can be a mesh, Bezier and NURBS surfaces, or multiple lines using open polygons.
Placing a Grid in the viewer
| To... | Do this |
|---|---|
|
Place the grid anywhere in the scene |
|
|
Place the grid at the origin |
Press
Ctrl
+
|
The grid can be moved once it is placed by either dragging it in the scene view or changing the values in the parameter editor.
Grid Handles
There are special handles available at the geometry level for the grid object that allow you to stretch and squash it.
-
Move to the geometry level by double clicking
the grid node in the network editor or by clicking the Jump to Operator button on the operation controls toolbar. -
Drag the handles to squash or stretch the grid.
Parameters

Primitive Type |
Type of Geometry to create. In the case of Points, no geometry is created. Instead, free floating points are created in the same order as if the geometry had been made. |

The Grid SOP is a very commonly used primitive, especially as a particle source. It is very versatile and has many surface parameterization options.
In this example, there is a series of grids with alternative Primitive Types and Connectivity.
