You can use `spin=` to rotate around the Z axis:
You can use `spin=` to rotate around the Z axis **after** anchoring:
```openscad-3D
include <BOSL2/std.scad>
cube([50,40,20], anchor=FRONT, spin=30);
```
3D objects also gain the ability to use an extra trick with `spin=`;
if you pass a list of `[X,Y,Z]` rotation angles to `spin=`, it will
rotate by the three given axis angles, similar to using `rotate()`:
```openscad-3D
include <BOSL2/std.scad>
cube([50,40,20], anchor=FRONT, spin=[15,0,30]);
```
3D objects also can be given an `orient=` argument as a vector, pointing
to where the top of the shape should be rotated towards.
