The `grid2d()` command will let you spread copies across both the X and Y
The `grid_copies()` command will let you spread copies across both the X and Y
axes at the same time:
```openscad-2D
include <BOSL2/std.scad>
grid2d(20, n=6) sphere(d=10);
grid_copies(20, n=6) sphere(d=10);
```
The spacing can be separately specified for both the X and Y axes, as can
the count of rows and columns:
```openscad-2D
include <BOSL2/std.scad>
grid2d([20,30], n=[6,4]) sphere(d=10);
grid_copies([20,30], n=[6,4]) sphere(d=10);
```

You can get the alternate stagger pattern if you set `stagger="alt"`:

grid2d(20, n=[12,6], stagger="alt") sphere(d=10);

You can alternately specify a grid using size and spacing:

You can also make grids by specifying size and column/row count:
```openscad-2D
include <BOSL2/std.scad>
grid2d(n=5, size=100) sphere(d=10);

```openscad-2D

grid2d(n=[4,5], size=[100,80]) sphere(d=10);
grid_copies(n=[4,5], size=[100,80]) sphere(d=10);

Finally, the `grid_copies()` command will let you give a polygon or region shape
to fill with items. Only the items in the grid whose center would be inside
the polygon or region will be created. To fill a star shape with items, you
can do something like:
```openscad-3D
include <BOSL2/std.scad>
poly = [for (i=[0:11]) polar_to_xy(50*(i%2+1), i*360/12-90)];
grid2d(5, stagger=true, inside=poly) {
grid_copies(5, stagger=true, inside=poly) {
cylinder(d=4,h=10,spin=90,$fn=6);
}
