Grab
What is it about?
This page documents the Grab brush for sculpting in Cinema 4D. It pulls mesh regions directly to a new position — from fine spikes to broad proportion changes like shaping a chin or skull on low subdivision levels.
As the name suggests, this brush can be used to grab part of the mesh and pull it into the desired position.
On the one hand you can pull a narrow spike from a surface and on the other hand you can use a large Grab brush to sculpt globally (on Layers with low subdivision), e.g., to shape a character's chin or head.
An overview of all available brushes can be found here: Brushes.
