Sculpt is a function for moving parts of a surface forward or backwards.
It can smooth the simulation by helping with pleats and placements.
3D Viewport > Surface > Move Gizmo > Ctrl + Move Mouse in White Circle
- Enable Move Gizmo in All /Surfaces Selection Mode, then select the surface to sculpt.
- Press down on the Ctrl key, then move the mouse forwards or backwards inside the white circle at the center of the gizmo.
- Parts of the surface will change by moving forward or backward based on the round circle of the gizmo.
