Proportional Edit
Fleeting- External reference: https://docs.blender.org/manual/en/latest/editors/3dview/object/editing/transform/control/proportional_edit.html
- see,
Proportional Edit is a way of transforming selected elements (such as vertices) while having that transformation affect other nearby elements
You can increase or decrease the radius of the proportional editing influence with the mouse wheel WheelUp, WheelDown or PageUp, PageDown respectively
Disable O, Alt-O
Enable O, Alt-O
Rather than using a radius only, the proportional falloff spreads via connected geometry. This means that you can proportionally edit the vertices in a finger of a hand without affecting the other fingers
While editing, you can change the curve profile used by either using the Mesh ‣ Proportional Falloff submenu, using the header icon Falloff menu, or by pressing Shift-O to toggle between the various options
