Group Visible

From ZBrush Info

Group Visible will group the entire visible part of the mesh. This feature is used to create your own grouping information.

Create Your Own Group

1. Make sure your model is in edit mode on the canvas.
2. Press CTRL+SHIFT and drag out a selection marquee over your model. Please note, you can turn on Transform: Lasso before performing this action to use a lasso selection tool instead.
3. Release CTRL+SHIFT when you have an area of the model selected. This will hide everything but the area of the model that was inside your marquee selection.
4. Press Tool: Polygroups: Group Visible.
5. Press CTRL+SHIFT and tap the left mouse button outside of the model to show the entire model again.
