To use Soft Selection

Select the Select Tool, Move Tool, Rotate Tool or Scale Tool.
Select the components you want to transform.
Press b on your keyboard.
Soft Selection mode is turned on.
Press and hold b + left or right to increase or decrease the size of the falloff area.
The cursor changes to a circle representing the size of the falloff area.
Use the selected tool to transform the components.

You can also turn on Soft Selection and modify the Soft Selection settings from the Tool Settings Editor for all the transformation tools. Alternatively, you can use the transformation tool marking menus (for more information see Transform marking menus).

NoteUnlike the Soft Modification deformer, which can be used to achieve many of the same results, Soft Selection does not create history nodes.
