model that shows inside the edges of the content. However, the cross-
section can be implemented to display the interior part of the model; for
instance, you can use it to create a section in a car model to view the inside
parts. You can also use it to create an animation efect that cuts the 3D
model or displays the 3D model gradually, as shown later in this chapter.
The Cross Section tool includes diferent settings that let you customize how
the planes cut or intersect the 3D object. Before showing an example of
how the cross section works, here are the diferent options available under
the Cross Section tool (Figure 12.3):
•
The Planar checkbox shows or hides the plane that slices the 3D object.
Also, you can set its color and opacity from the Opacity slider.
•
The Intersection checkbox adds a highlight to the part that intersects
with the plane; you can change the highlight color by clicking the color
box next to the checkbox.
•
The Flip Cross Section option, located next to the Intersection color
selector, lets you invert the hidden part of the model.
•
The X, Y, and Z axes specify the axes of the plane that will rotate and
move around it.
•
The Ofset value lets you move the plane; the direction of the plane
movement is based on the axis of the plane.

Section option enabled.
•
Tilt A and Tilt B rotate the plane around its axis; this afects the slicing
direction of the 3D object.
