Adjust Clipping Planes – A clipping plane can be moved into the model and 'hide' the
part of the model on one side of the plane. This is useful for focusing on a 'slice' of a
model. The image in Figure 35 is a living room model with the vertical a clipping plane
moved 'down' so only the bottom of the model is visible – giving a good view of the
room's floor plan.

When Adjust Clipping Planes is selected, the dialog box in Figure 36 appears. From this you
can choose which axis to clip along (x, y, or z), and from which direction by moving the
sliders.
Instead of using a clipping plane based on the coordinate axes, you can choose to use a plane
annotation that has been added to the scene. Select that plane in the scene tree or in the
window and then pick Use Selected Plane in the clip window. These planes are often useful
because they can be parallel to the floor or a wall and produce orthogonal cross sections of a
scene. If you want to change to a different plane, select a different plane and click on the
Use Selected Plane button again.
You can also move the visible slice by moving the slider at the bottom of the clipping plane
window. When the clipping plane window is closed, the clipping planes are no longer active.
