Face
Faces are the faces that make up the mesh, and moving or editing a face affects the elements associated with it.
You can view the properties of a Face by pressing the keyboard shortcut Shift+3, or by using the buttons at the top of the scene.
Face Element Group Properties
These are the properties that are displayed for the Element group when a Face is selected.
Extrude Option
Properties that allow you to choose how the face is extruded when using the Extrude Tool.
The Extrude Tool can be used to extrude or extrude faces using the keyboard shortcut Shift+Click Drag.
Gizmo Default
This is the default property for the Extrude Tool, which causes the Extrude Tool to run based on the gizmo.
Individual Normal
The Extrude Tool will run on an individual face-by-face basis, aligned with the face's normal direction.
The difference with the Vertex Normal property is that for Individual Normal, the Extrude tool is run for each face, so the selected faces are all extruded or pushed apart.
Vertex Normal
The Extrude tool is run in the normal direction of the faces.
Average Normal
Runs the Extrude tool in the average normal direction of the selected faces.
Display
This property allows you to choose how the mesh is displayed.
XRay Mode
Displays faces as translucent.
Hide Edge Overlay
Allows you to show or hide edges.
Select
Property that allows you to set how the face is selected.
Backface Select
Allows you to set whether opposite faces are selected.
When the Backface Select property is off, opposite faces are not selected.
When the Backface Select property is on, opposite faces will be selected as well.
Camera Based Select
This property selects only the currently visible face based on the camera.
When the Camera Based Select property is off, faces hidden by the camera are also selected.
When the Camera Based Select property is on, faces that are hidden by the camera are not selected.
Soft Select
This property selects faces in the Scene that are adjacent to the selected face based on their weight.
The selected faces and the range you set based on the weight are colored, usually a soft circle.
Soft Selection
Properties that use Soft Selection.
Soft Selection Curve
A graph-like property that determines the shape of the Soft Selection. Tap the graph next to the Soft Selection Curve property to edit it.
Example of Curve shape
Examples of how the selection shape changes depending on the Curve shape.

Example 2
Soft Selection Range
A property that sets the range over which the soft selection is applied from the selected face.
In Unity, 1m = 1.0, so for 0.5, it will select up to 50cm from the selected face.
Smoothing Group
This is a property that allows you to manage faces as a group, making them appear to be connected or disconnected from each other.
A group of selected faces will smoothly connect surfaces, while other groups will appear disconnected.
Proper use of the Smoothing Group property can help you achieve smooth surfaces with a small number of faces, and can help with optimization.
Auto Smooth
This property automatically sets a smoothing group between selected faces.
Clear
This property resets all currently set smoothing groups.
Selected Smoothing Group
This property selects the face set to the group when the button corresponding to the group is pressed.
In addition to smoothing, the Selected Smoothing Group property can also be used to manage complex models in groups, as it makes it easy to select faces.
Selected Smoothing Group Example
Since a single face can have more than one group, you can also select them as shown in the example below
