Cutting a cube

Task

Create a cube and intersect it with a plane to observe the intersection polygons.

1.		Enter `a x + b y + c z = d` into the Input Bar to create a plane.
2.		After pressing Enter sliders for values a, b, c and d will be created automatically.
3.		Select the Cube tool from the 3D Graphics View Toolbar and click on points (0, 0, 0) and (2, 0, 0) in the 3D Graphics View.
4.		Select the Intersect Two Surfaces tool and click directly on one intersection segment to display the whole intersection polygon of the plane and the cube.
5.		Select the Move tool and change the slider values by dragging the point on the line.
6.		Hide the axes and the xOy-plane through the Style Bar. Select the Rotate 3D Graphics View tool and drag the 3D Graphics View to rotate the cube and the plane.
