+## Clip objects
+
+You can clip any object represented in the plotter by defining a ``Plane`` object that
+intersects the target object.
+
+```{code-cell} ipython
+
+from ansys.geometry.core.math import Plane, Point3D
+ph = PlotterHelper()
+
+# Define PyAnsys Geometry box
+box2 = Sketch()
+box2.box(Point2D([-10, 20], UNITS.m), Quantity(10, UNITS.m), Quantity(10, UNITS.m))
+box_body2 = design.extrude_sketch("JustABox", box2, Quantity(10, UNITS.m))
+
+# Define plane to clip the box
+origin = Point3D([-10., 20., 5.], UNITS.m)
+plane = Plane(origin=origin, direction_x=[1, 1, 1], direction_y=[-1, 0, 1])
+
+# Add the object with the clipping plane
+ph.add(box_body2, clipping_plane=plane)
+ph.plot()
+```

 ## Select objects interactively
 
 PyAnsys Geometry's plotter supports interactive object selection within the scene.
