Adding Planes

Prerequisite
Introduction
A plane is simply a rectangle. It is even simpler than a box because it is only 2-dimensional. That is, it does not have any thickness. Therefore, planes can be used to represent thin rectangle objects around us, such as the ground surface, a picture on the wall, etc.
The “Add Plane” Block
Since planes are 2-dimensional objects, you only need to specify their sizes in the X and Y dimensions.
A Plane’s Facing Direction
By default, a plane will be facing up (the positive Z direction) when it is added. One thing special about planes is that their “back faces” is transparent by default.
This is especially useful when you use a plane as the ground, since you can see through it when your camera is below the ground.
However, if you do not want the plane to be transparent, you can use the material setting block to make sure the back face is drawn.
Position and Rotation of a Plane
Although planes are 2-dimensional, you can still move them to different positions or rotate them to different directions in the 3D space. You can try it using the gizmos like this:
