Deform Group

The Deform group includes brush-like tools for surface manipulation, rather than editing at the element level.

Brush tools allow you to adjust the brush size by moving the mouse up or down while holding the Shift key or using shortcuts like [,].

Relax

The Relax Brush evens out vertex spacing while maintaining the shape.

Smooth

Flatten

Move

The Move Brush moves vertices.

Pinch

The Pinch Brush brings vertices closer together, creating sharper edges.
