};Description
DVplane_crop subsets a field by outputting all whole cells that are inside or outside a volume created by an unlimited number of slice planes.
Input
An array of references to any number of Plane_Grids that will slice the volume. A Plane_Grid is defined as Grid_Unif+Space2+Dim2. It is therefore any 2D uniform grid.
An integer. When this value is not 0, then the entire cell intersected by a plane is output. If it is 0, then the entire cell is not output.
An integer. When this value is not 0, the cells inside the slicing planes are output. If it is 0, then the cells outside the slicing planes are output.
Output
The output is a new Mesh and Node_Data that is the plane-cropped input Mesh, plus any Node_Data for the output nodes. The mesh contains a reference to the input field's xform.
