3.1 X-Ray and shading modes for modeling

As you start handling 3D objects in Blender for modeling tasks, it will

become important to use a tool called X-Ray to make your selections

easier in those contexts. Why is X-Ray mode important for modeling?

The mode helps you edit certain types of objects occluded by existing

geometry.

For instance, if you get a simple Cube in your 3D Viewport and try to

select the bottom vertices using the B Key, you will notice that only the

visible vertices become selected. By using X-Ray mode, you can easily

select all vertices—even those behind existing faces.

To enable X-Ray Mode, use the button located at the 3D Viewport

header, on the left of the shading modes (Figure 3.1).
